Energy Transformations

Front

What happens to kinetic energy as the speed of an object increases?

Back

The kinetic energy becomes greater.

Front

What is an example of a chemical to mechanical energy transformation?

Back

Eating a big breakfast before a race.

Front

What type of energy is stored by objects that stretch or compress?

Back

Elastic potential energy.

Front

What are the energy transformations that occur when a lamp is plugged in and turned on?

Back

Electrical → thermal → light.

Front

What principle states that energy cannot be created or destroyed during transformations?

Back

The law of conservation of energy.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

What type of energy transformation occurs in a battery-powered device?

Back

Chemical → electrical.

Front

What is an example of gravitational potential energy?

Back

A book on a shelf.

Front

What is the difference between elastic potential energy and gravitational potential energy?

Back

Elastic potential energy is stored in objects that can stretch or compress, while gravitational potential energy is related to an object's height above the ground.
