Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula 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. For example, a rock at the top of a hill has gravitational potential energy.

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass. If two objects are moving at the same velocity, the one with greater mass will have more kinetic energy.

Front

What happens to Kinetic Energy if velocity is doubled?

Back

If the velocity of an object is doubled, its kinetic energy increases by a factor of four, since KE = 1/2 mv².

Front

What is the unit of energy?

Back

The unit used to measure energy is the joule (J).

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when a roller coaster goes down a hill, converting potential energy at the top into kinetic energy as it speeds up.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy due to its deformation.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is directly related to the square of the velocity; as velocity increases, kinetic energy increases.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.
