Energy and Motion

Front

What type of force is acting on an elevator moving up?

Back

Unbalanced force is acting on the elevator.

Front

Does more friction equal more heat during a collision?

Back

Yes, more friction generates more heat.

Front

What happens to an object if its kinetic energy increases?

Back

The object will move faster.

Front

What happens to kinetic energy during a collision?

Back

Some kinetic energy is transformed into sound energy and heat.

Front

What will happen to a moving object if no unbalanced force acts on it?

Back

It will continue moving.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is inertia?

Back

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

Front

What is the relationship between speed and kinetic energy?

Back

As speed increases, kinetic energy increases.
