Kinetic and Potential Energy Flashcard

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, which depends on its mass and velocity.

Front

How is gravitational potential energy calculated?

Back

Gravitational potential energy (PE) can be calculated using the formula: PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

Front

What is an example of kinetic energy?

Back

A tennis ball rolling across the court is an example of kinetic energy.

Front

What happens to energy when an object falls?

Back

As an object falls, its gravitational potential energy is converted into kinetic energy.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; if the speed doubles, the kinetic energy increases by four times.

Front

What is an example of potential energy?

Back

A 45lb dog sitting in an oak tree has gravitational potential energy due to its height above the ground.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
