What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state, which can be converted into kinetic energy when the object is in motion.

Front

Give an example of Potential Energy.

Back

A rock sitting on top of a high ledge.

Front

What is the relationship between height and Potential Energy?

Back

The higher an object is positioned, the more Potential Energy it has due to the gravitational force acting on it.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion, which depends on the mass of the object and the speed at which it is moving.

Front

How is Mechanical Energy defined?

Back

Mechanical Energy is the sum of Potential Energy and Kinetic Energy in an object that is used to do work.

Front

What is the formula for calculating Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

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.

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating objects, which creates sound waves that travel through a medium.

Front

What are vibrations in the context of sound?

Back

Vibrations are rapid back-and-forth movements of particles in a medium that create sound waves.

Front

When does an object have the most Potential Energy when rolling down a ramp?

Back

An object has the most Potential Energy at the top of the ramp.
