Kinematics Test Review

Front

What is Kinematics?

Back

Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

What does a positive velocity indicate?

Back

A positive velocity indicates that an object is moving in the positive direction of the chosen coordinate system.

Front

What does a negative velocity indicate?

Back

A negative velocity indicates that an object is moving in the negative direction of the chosen coordinate system.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no other forces acting on it.

Front

How does speed change in free fall?

Back

In free fall, the speed of an object increases by approximately 10 m/s for each second it falls.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how an object's velocity changes over time, with the slope representing acceleration.

Front

What does a horizontal line on a velocity-time graph indicate?

Back

A horizontal line indicates that the object is moving at a constant velocity.
