Physics Scientific Method Quiz Questions

2.

The steps of the scientific method are

Problem, hypothesis, test, results, theory
Test, problem, theory, hypothesis, results
Results, hypothesis, test, problem, theory
Problem, theory, hypothesis, test, results

Correct Answer

A. Problem, theory, hypothesis, test, results

Explanation

The scientific method is a systematic approach used to investigate and understand phenomena. It starts with identifying a problem or question that needs to be answered. Then, a theory is formulated based on existing knowledge and observations. A hypothesis is then proposed as a possible explanation for the problem. Next, experiments or tests are conducted to gather data and evidence. Finally, the results of the experiments are analyzed, and a theory is developed based on the evidence gathered. Therefore, the correct order of the steps in the scientific method is problem, theory, hypothesis, test, results.

When something speeds up it is

Speeding
Accelerating
Velocity
Decelerating

Correct Answer

A. Accelerating

Explanation

When something speeds up, it means that its velocity is increasing over time. Acceleration is the rate at which velocity changes, so when an object accelerates, it means that its velocity is increasing. Therefore, the correct answer is "accelerating."

10 m/s2 is the given number for

Gravity
Acceleration
Velocity
Speed

Correct Answer

A. Gravity

Explanation

The given number, 10 m/s2, represents the acceleration due to gravity. This value is commonly used to describe the rate at which objects fall towards the Earth. It indicates that for every second an object is in free fall, its velocity increases by 10 meters per second. Therefore, the correct answer is gravity.

What units can NOT be used to measure speed?

Km/hr
M/s
ML/L
Mi/hr

Correct Answer

A. ML/L

Explanation

The units mL/L cannot be used to measure speed because they are units of volume per unit volume. Speed is a measure of distance traveled per unit time, so mL/L does not represent a valid measurement for speed.

An object thrown up in the air has zero velocity when it ____

Is released.
At its highest point.
At its lowest point.
At its returning point.

Correct Answer

A. At its highest point.

Explanation

When an object is thrown up in the air, it initially has an upward velocity. As it reaches its highest point, its velocity decreases and eventually becomes zero. This is because at the highest point, the object momentarily comes to a stop before starting to fall back down due to the force of gravity. Therefore, at its highest point, the object has zero velocity.

A parabola is the path of an object effected by

Speed and gravity
Free fall
M/s
Force

Correct Answer

A. Speed and gravity

Explanation

A parabola is the path of an object affected by speed and gravity. When an object is thrown or launched into the air, it follows a curved trajectory due to the combined influence of its initial speed and the force of gravity pulling it downwards. This curved path resembles a parabola. The speed determines how far the object will travel horizontally, while gravity determines how quickly it will fall vertically. Thus, both speed and gravity play a significant role in shaping the path of the object, resulting in a parabolic trajectory.

There are 2 objects at the same heighth, one dropped and one thrown. Which will hit the ground first?

The dropped one
The thrown one
Both at same time
Neither

Correct Answer

A. Both at same time

Explanation

Both objects will hit the ground at the same time. This is because the only force acting on the objects is gravity, which causes them to accelerate towards the ground at the same rate regardless of their initial velocities. Therefore, both objects will reach the ground simultaneously.

A quantity that shows both motion and direction is a

Theory
Acceleration
Scalar
Vector

Correct Answer

A. Vector

Explanation

A vector is a quantity that shows both motion and direction. Unlike a scalar, which only has magnitude, a vector has both magnitude and direction. In the context of physics, velocity and force are examples of vector quantities because they have both magnitude (speed or strength) and direction (the direction of motion or force). Therefore, a vector is the correct answer in this case.

The formula for rate(velocity)

V=D X T
G= 1/2 D X T
V= V1 + V2 / 2
None of the above

Correct Answer

A. V=D X T

Explanation

The formula for rate or velocity is given by V = D x T, where V represents velocity, D represents distance, and T represents time. This formula states that velocity is equal to the product of distance and time.
