## Physical Motion Questions and Answers

• 1.

### ______ is a unit of speed:

• A.

M/s

• B.

S

• C.

Kg

• D.

Hr

A. M/s
Explanation
The unit m/s represents meters per second, which is a measure of speed. It indicates how many meters an object travels in one second. This unit is commonly used in physics and engineering to describe the velocity of an object or the rate at which it changes its position. The other options (s, kg, and hr) do not represent units of speed but rather represent units of time (seconds), mass (kilograms), and time (hours), respectively.

### If a total distance of 750 m is covered in a time interval of 25 s, the average speed is ______?â€¨

• A.

3,974 mph

• B.

3 mph

• C.

30 mph

• D.

30 m/s

D. 30 m/s
Explanation
The average speed is calculated by dividing the total distance covered by the time taken. In this case, the total distance covered is 750 m and the time interval is 25 s. Therefore, the average speed is 750 m / 25 s = 30 m/s.

### ______________ describes how fast something is going, whereas, __________ describes how fast something is going and in a certain direction.â€¨

• A.

Speed, velocity

• B.

Rate, speed

• C.

Rate, velocity

• D.

Speed, acceleration

A. Speed, velocity
Explanation
Speed is a scalar quantity that describes how fast something is going, regardless of its direction. On the other hand, velocity is a vector quantity that not only describes how fast something is going but also includes its direction. Therefore, speed and velocity are different in that velocity takes into account both speed and direction, whereas speed only considers the magnitude of the motion.

### Which of the following is a measure of velocity?

• A.

30 s

• B.

30 South

• C.

30 m/s

• D.

30 m/s, South

D. 30 m/s, South
Explanation
The correct answer is 30 m/s, South. Velocity is a measure of the rate at which an object changes its position. It includes both the speed and direction of an object's motion. In this case, the answer "30 m/s, South" indicates that the object is moving at a speed of 30 meters per second in the south direction.

### If a person walking at 2 m/s for 12 s he/she would travel a distance of ________.

• A.

24 m

• B.

6 m

• C.

4 m

• D.

A. 24 m
Explanation
If a person is walking at a speed of 2 m/s for 12 seconds, we can calculate the distance traveled by multiplying the speed by the time. So, 2 m/s * 12 s = 24 m. Therefore, the person would travel a distance of 24 meters.

### 8. The ______ of a distance versus time graph is speed.â€¨

• A.

Slope

• B.

Y-intercept

• C.

Origin

• D.

A. Slope
Explanation
The slope of a distance versus time graph represents the rate at which an object is moving, which is the definition of speed. The steeper the slope, the faster the object is moving, and the flatter the slope, the slower the object is moving. Therefore, the slope of a distance versus time graph is directly related to the speed of the object.

Rate this question:

• 7.

### Does the speedometer of a car read average speed or instantaneous speed?

• A.

Average speed

• B.

Instantaneous speed

B. Instantaneous speed
Explanation
The speedometer of a car reads instantaneous speed, which means it shows the speed of the car at any given moment. It provides real-time information about how fast the car is currently moving. In contrast, average speed is calculated by dividing the total distance traveled by the total time taken, and it gives an overall measure of the car's speed over a period of time. However, the speedometer only displays the instantaneous speed, allowing the driver to know the current speed at any given moment.

### An airplane is flying at 635 km per hour at an altitude of 35,000 m. It is currently over Kansas and is approximately 16 minutes ahead of its scheduled arrival time. What is its velocity?

• A.

635 km/h

• B.

16 m/min

• C.

35 000 m/s

• D.

This cannot be determined without further information about its direction.

• E.

This cannot be determined without further information about its time.

D. This cannot be determined without further information about its direction.
Explanation
The velocity of an object is a vector quantity that includes both magnitude and direction. In this question, we are given the speed of the airplane (635 km/h) and its altitude (35,000 m), but we do not have any information about its direction. Therefore, without knowing the direction in which the airplane is flying, we cannot determine its velocity.

Rate this question:

### The difference between speed and velocity is that velocity includes

• A.

Direction

• B.

Distance

• C.

Time

• D.

Weight

• E.

Force

A. Direction
Explanation
Velocity is a vector quantity that includes both magnitude and direction. Speed, on the other hand, is a scalar quantity that only includes magnitude. Therefore, the main difference between speed and velocity is that velocity includes direction.

Rate this question:

### Which of the following does notindicate velocity?

• A.

14 ft/s SSE

• B.

40 mi/h toward the town square along the main street

• C.

80 km/h going from New York toward New Jersey

• D.

28 miles from Los Angeles to Catalina Island

• E.

All of these indicate velocity.

D. 28 miles from Los Angeles to Catalina Island
Explanation
The given options describe different movements with specific directions and distances. However, the option "28 miles from Los Angeles to Catalina Island" does not indicate velocity because it only provides the distance between two locations without any information about the direction or time taken to cover that distance. Velocity is a vector quantity that includes both speed and direction, and this option lacks the direction component.

### When an object slows down, its acceleration is

• A.

Positive.

• B.

Centripetal.

• C.

Negative.

• D.

Constant.

• E.

Centrifugal.

C. Negative.
Explanation
When an object slows down, its acceleration is negative. This is because acceleration is defined as the rate of change of velocity, and velocity is a vector quantity that includes both magnitude and direction. When an object slows down, its velocity decreases, which means there is a negative change in velocity over time. Therefore, the acceleration is negative.

### Moving from 0 m/s to 25 m/s in 8.0 s equals an average acceleration of

• A.

0.32 m/s.

• B.

0.32 m/s2.

• C.

3.1 m/s.

• D.

3.1 m/s2.

• E.

None of these are correct.

D. 3.1 m/s2.
Explanation
The average acceleration can be calculated by dividing the change in velocity by the time taken. In this case, the change in velocity is 25 m/s (final velocity) - 0 m/s (initial velocity) = 25 m/s. The time taken is 8.0 s. Dividing the change in velocity by the time taken gives us 25 m/s / 8.0 s = 3.1 m/s2. Therefore, the correct answer is 3.1 m/s2.

### Roger and Natalie travel in similar cars. Roger's car drives the two miles to school in 7.5 minutes. Natalie drives the same distance in the opposite direction but in only 6.5 minutes. What is true of their velocities?

• A.

Roger and Natalie have velocities with the same magnitude only.

• B.

Natalie's velocity is greater in magnitude than Roger's velocity.

• C.

Roger's velocity is greater in magnitude than Natalie's velocity.

• D.

Roger and Natalie have velocities with the same direction and magnitude.

B. Natalie's velocity is greater in magnitude than Roger's velocity.
Explanation
Since both Roger and Natalie are traveling the same distance, the ratio of distance to time can be used to compare their velocities. Roger's velocity is calculated as 2 miles / 7.5 minutes = 0.2667 miles/minute. Natalie's velocity is calculated as 2 miles / 6.5 minutes = 0.3077 miles/minute. Therefore, Natalie's velocity is greater in magnitude than Roger's velocity.

### Which car is accelerating?

• A.

A car that is unmoving

• B.

A car that goes around a curve at a constant speed

• C.

A car that travels in straight line at a constant speed

• D.

A car that is set to a constant speed of 60 miles per hour

B. A car that goes around a curve at a constant speed
Explanation
A car that goes around a curve at a constant speed is the correct answer. Even though the car's speed remains constant, it is still accelerating because acceleration is defined as any change in velocity, including changes in direction. In this case, the car is constantly changing its direction as it goes around the curve, which means it is experiencing acceleration.

Rate this question:

### Which to the following best describes an object with constant velocity?

• A.

It is changing direction

• B.

Its acceleration is increasing

• C.

Its acceleration is zero

• D.

Its acceleration is negative

C. Its acceleration is zero
Explanation
An object with constant velocity means that its speed and direction are not changing. If the acceleration is zero, it means that there is no change in velocity over time. Therefore, the object is maintaining a constant velocity.

• A.

Straight and sloping up to the right

• B.

Straight and sloping down to the right

• C.

Straight and horizontal

• D.

Curved up to the right

C. Straight and horizontal
Explanation
The slope of an object accelerating uniformly (at a constant rate) on an acceleration vs. time graph is straight and horizontal. This means that the acceleration remains constant over time. The graph would show a straight line parallel to the x-axis, indicating that the object is experiencing a constant acceleration and not changing its rate of acceleration.

Rate this question:

### The change in position of an object is known as its _______.

displacement
Explanation
Displacement refers to the change in position of an object. It is a vector quantity that takes into account both the magnitude and direction of the change in position. It is different from distance, which only considers the magnitude of the change. Displacement is often represented by an arrow pointing from the initial position to the final position of the object.

Rate this question:

### A runner runs seven times around a track. If the track is 0.25 miles long, his displacement is ________ miles.

0, zero
Explanation
Since the runner starts and finishes at the same point, his displacement is zero. Displacement refers to the change in position from the starting point to the final point, and in this case, there is no change as the runner returns to the starting point after completing seven laps. Therefore, the displacement is zero miles.

Rate this question:

• 20.

### The term for how quickly an object's velocity changes is known as __________.

acceleration
Explanation
Acceleration refers to the rate at which an object's velocity changes. It is a measure of how quickly an object speeds up, slows down, or changes direction. In other words, it quantifies the change in velocity over time. Therefore, acceleration is the appropriate term to describe how quickly an object's velocity changes.

Rate this question:

### Which of the following statements describes a situation in which the car is undergoing an acceleration?

• A.

A car slows down as it approaches a red light.

• B.

A car speeds up as the light turns green.

• C.

A car makes a right hand turn at a constant speed.

• D.

A car maintains its speed as it travels down a straight road.

A. A car slows down as it approaches a red light.
B. A car speeds up as the light turns green.
C. A car makes a right hand turn at a constant speed.
Explanation
A car slows down as it approaches a red light and a car speeds up as the light turns green both describe situations in which the car is undergoing an acceleration. In both cases, the car's velocity is changing, either decreasing or increasing, which indicates acceleration. A car making a right-hand turn at a constant speed does not involve a change in velocity, so there is no acceleration in this situation. A car maintaining its speed as it travels down a straight road also does not involve a change in velocity, so there is no acceleration in this situation either.
