Reminder:

One joule in everyday life is approximately:
the energy required to lift a small apple one meter straight up.
the energy released when that same apple falls one meter to the ground.
the energy released as heat by a person at rest, every hundredth of a second.
one hundredth of the energy a person can receive by drinking a drop of beer.
the kinetic energy of an adult human moving at a speed of about a handspan every second.
the kinetic energy of a tennis ball moving at 23 km/h (14 mph).[2]
