Force and Motion Unit Review 1

Front

What happens to potential energy (PE) and kinetic energy (KE) as a boulder rolls down a hill?

Back

PE decreases and KE increases.

Front

At which positions of a pendulum is the potential energy the highest?

Back

Positions 1 and 5.

Front

What can be concluded if an object is moving at a constant speed?

Back

The object's speed does not change over time.

Front

What is an example of an object that has only potential energy?

Back

A boulder resting on top of a cliff.

Front

When does an airplane convert kinetic energy to potential energy?

Back

When it goes to a higher altitude.

Front

Define potential energy (PE).

Back

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

Front

Define kinetic energy (KE).

Back

Kinetic energy is the energy of an object in motion.

Front

What is the relationship between PE and height?

Back

As height increases, potential energy increases.

Front

What is the relationship between KE and speed?

Back

As speed increases, kinetic energy increases.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car or a running person.
