Harnessing Human Energy Ch. 1 Review

Front

What is a system?

Back

A set of interacting parts forming a complex whole.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

Give an example of kinetic energy.

Back

A flying soccer ball.

Front

What happens to a wind-up toy when it is wound up and released?

Back

It has kinetic energy.

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

How is potential energy different from kinetic energy?

Back

Potential energy is stored energy, while kinetic energy is energy of motion.

Front

What is an example of potential energy?

Back

A stretched rubber band.

Front

What is the relationship between potential energy and kinetic energy in a pendulum?

Back

At the highest point, it has maximum potential energy and minimum kinetic energy; at the lowest point, it has maximum kinetic energy and minimum potential energy.

Front

What is energy transformation?

Back

The process of changing energy from one form to another.

Front

What is an example of energy transformation?

Back

A battery converting chemical energy into electrical energy.
