Force & Motion Amplify Review

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, causing it to slow down and eventually stop.

Front

How can the motion of an object change?

Back

The motion of an object can change by slowing down, speeding up, or changing direction.

What happens to the force experienced by an object when its mass increases?

Back

When the mass of an object increases, it requires a greater force to change its motion.

What is velocity?

Back

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

Front

What is the relationship between mass and force in a collision?

Back

In a collision, the object with greater mass will experience a stronger force if it changes speed by the same amount as a lighter object.

What is inertia?

Back

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