Velocity And Speed! Ultimate Trivia Quiz

1. ______ is a unit of speed:

M/s

S

Kg

Hr

The correct answer is m/s. The unit m/s represents meters per second, which is a common unit of speed. It measures the distance traveled in meters divided by the time taken in seconds. This unit is widely used in physics and engineering to express the velocity of objects or the speed of motion.

Explanation

The correct answer is m/s. The unit m/s represents meters per second, which is a common unit of speed. It measures the distance traveled in meters divided by the time taken in seconds. This unit is widely used in physics and engineering to express the velocity of objects or the speed of motion.

2. How long would it take to travel 50 km traveling at a speed of 10 km/hr? 

3 hours

1 hour

5 hours

50 hours

At a speed of 10 km/hr, it would take 5 hours to travel 50 km. This can be calculated by dividing the distance (50 km) by the speed (10 km/hr), which gives the time taken in hours.

Explanation

At a speed of 10 km/hr, it would take 5 hours to travel 50 km. This can be calculated by dividing the distance (50 km) by the speed (10 km/hr), which gives the time taken in hours.

3. ______________ describes how fast something is going, whereas, __________ describes how fast something is going and in a certain direction. 

Speed, velocity

Rate, speed

Rate, velocity

Speed, acceleration

Speed refers to how fast an object is moving, regardless of its direction. On the other hand, velocity not only considers the speed of an object but also takes into account the direction in which it is moving. Therefore, speed describes the magnitude of the motion, while velocity describes both the magnitude and direction.

Explanation

Speed refers to how fast an object is moving, regardless of its direction. On the other hand, velocity not only considers the speed of an object but also takes into account the direction in which it is moving. Therefore, speed describes the magnitude of the motion, while velocity describes both the magnitude and direction.

4. SI unit for speed is the ________. 

In/ hour

M/s

Cm/min

None of the answers

The SI unit for speed is meters per second (m/s). This unit is commonly used to measure the rate at which an object covers a certain distance in a specific amount of time. It is a standard unit in the International System of Units (SI) and is widely used in scientific and everyday measurements of speed. The other options, such as in/hour and cm/min, are not SI units for speed and are less commonly used in scientific contexts.

5. If a total distance of 750 m is covered in a time interval of 25 s, the average speed is ______? 

3,974 mph

3 mph

30 mph

30 m/s

The average speed is calculated by dividing the total distance traveled by the time taken. In this case, the total distance covered is 750 m and the time interval is 25 s. By dividing 750 m by 25 s, we get the average speed of 30 m/s.

Explanation

The average speed is calculated by dividing the total distance traveled by the time taken. In this case, the total distance covered is 750 m and the time interval is 25 s. By dividing 750 m by 25 s, we get the average speed of 30 m/s.

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

24 m

6 m

4 m

None of the answers

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. Therefore, the person would travel a distance of 2 m/s * 12 s = 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. Therefore, the person would travel a distance of 2 m/s * 12 s = 24 m.

7. Which of the following is a measure of velocity?

30 s

30 South

30 m/s

30 m/s, South

The correct answer is 30 m/s, South. Velocity is a measure of the rate at which an object changes its position in a specific direction. In this case, the answer includes both the magnitude (30 m/s) and the direction (South), which are both necessary to fully describe the velocity of an object.

Explanation

The correct answer is 30 m/s, South. Velocity is a measure of the rate at which an object changes its position in a specific direction. In this case, the answer includes both the magnitude (30 m/s) and the direction (South), which are both necessary to fully describe the velocity of an object.

8. The speed at any instant of time is known as

Average speed

Velocity

Given speed

Instantaneous speed

The speed at any instant of time is known as instantaneous speed because it refers to the speed of an object at a specific moment or point in time. Unlike average speed, which is calculated over a given distance and time interval, instantaneous speed provides information about the object's exact speed at a particular instant. Velocity refers to the speed of an object in a specific direction, while given speed is not a commonly used term in physics.

9. The ______ of a distance versus time graph is speed. 

Slope

Y-intercept

Origin

None of the answers

The slope of a distance versus time graph represents the rate at which the distance is changing over time. In other words, it represents the speed at which an object is moving. A steeper slope indicates a higher speed, while a flatter slope indicates a slower speed. Therefore, the correct answer is slope.

10. How far would you travel moving at 12 m/s for 3.00 minutes? 

36.0 m

2160 m

40.0 m

36.0 miles

If you are traveling at a speed of 12 m/s for 3.00 minutes, you can calculate the distance traveled by multiplying the speed by the time. In this case, 12 m/s multiplied by 180 seconds (3 minutes) equals 2160 meters. Therefore, the correct answer is 2160 m.
