Energy Test Review

Front

Energy stored by objects due to their position above Earth’s surface.

Back

Gravitational potential energy is the energy stored in an object as it is raised above the ground, due to the force of gravity.

Front

As the kinetic energy in a substance increases, what happens to its temperature?

Back

The temperature of the substance increases as kinetic energy increases, indicating more movement of particles.

Front

Energy stored in chemical bonds is known as what?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds.

Front

At what position would a cyclist have the MOST kinetic energy?

Back

Position D has the most kinetic energy, as it is typically where the cyclist is moving fastest.

Front

Mechanical energy is the sum of which two types of energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as gravitational potential energy.

Front

What is the formula for gravitational potential energy?

Back

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

Front

What happens to potential energy as an object falls?

Back

As an object falls, its gravitational potential energy decreases while its kinetic energy increases.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance; higher temperature means higher kinetic energy.
