Energy Transformations

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is potential energy?

Back

Energy stored in an object due to its position or state, such as chemical energy in food or batteries.

Front

What is kinetic energy?

Back

Energy of an object in motion, which depends on its mass and velocity.

Front

What is an example of energy transformation in a toaster?

Back

Electrical energy is transformed into thermal energy.

Front

What type of energy does a battery store?

Back

Chemical energy.

Front

What is thermal energy?

Back

Energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.

Front

What is an example of a source of chemical energy?

Back

Food, batteries, and fossil fuels.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.

Front

What happens to energy during a transformation?

Back

It changes from one form to another but the total amount of energy remains constant.

Front

What is an example of a transformation from chemical to electrical energy?

Back

A battery converting chemical energy into electrical energy.
