Introduction to Energy

Front

What does the Law of Conservation of Energy state?

Back

Energy cannot be created or destroyed, it can only be transformed.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy.

Front

What is an energy transformation?

Back

An energy transformation occurs when energy changes from one form to another.

Front

What energy transformation occurs in a toaster?

Back

Electric energy is transformed into thermal energy.

Front

What are the two types of mechanical energy?

Back

Potential energy and kinetic energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy dependent on?

Back

Potential energy is dependent on an object's position and the forces acting on it.

Front

Give an example of a situation where potential energy is converted to kinetic energy.

Back

A roller coaster at the top of a hill has potential energy that converts to kinetic energy as it descends.

Front

What is the formula for kinetic energy?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter.
