Force & Motion Amplify ch 1-2 Review

Front

What force causes all objects to slow down and eventually stop?

Back

Friction

Front

What does a diagram of bumper cars tell us about the force applied to each passenger?

Back

The force exerted on each passenger was the same.

Front

What is speed in a particular direction called?

Back

Velocity

Front

What happens to the motion of an object when a strong force is applied in the same direction as its motion?

Back

The object will speed up.

Front

What type of force can cause a greater change in velocity?

Back

A stronger force.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

How does mass affect the acceleration of an object when a constant force is applied?

Back

Greater mass results in less acceleration for the same force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
