24-25 Energy Study Guide

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

Where is gravitational potential energy the lowest for an object on a hill?

Back

At the lowest point of the hill.

Front

What are the three methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

How does the mass of an object affect its gravitational potential energy?

Back

The gravitational potential energy increases with the mass of the object, given the same height.

Front

If Rock A has twice the mass of Rock B at the same height, how do their potential energies compare?

Back

Rock A has twice the potential energy of Rock B.

Front

What happens to chemical energy when you warm your hands by a fire?

Back

Chemical energy is converted into heat energy.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) = mass (m) × gravitational acceleration (g) × height (h).
