Front

What does the 1st Law of Thermodynamics state?

Back

Energy can never be created nor destroyed; it can only transform.

Front

Front

What is mechanical energy?

Back

The sum of potential and kinetic energy in an object.

Front

What is thermal energy?

Back

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

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of motion.

Front

What is an example of chemical energy?

Back

Energy stored in food, batteries, or fuels.
