Front

What happens to potential and kinetic energy as a pendulum swings from its highest to lowest position?

Back

The potential energy decreases while the kinetic energy increases.

Front

What is chemical energy?

Back

Chemical energy is stored in the bonds between atoms.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

Front

What is the relationship between potential and kinetic energy in a closed system?

Back

In a closed system, potential energy can be converted to kinetic energy and vice versa.

Front

What is an example of chemical energy?

Back

Food is an example of chemical energy, as it is stored in the bonds of molecules.

Front

What happens to energy in a power plant?

Back

Energy is transformed from chemical energy in coal to electrical energy.
