One joule in everyday life represents approximately:
the energy required to lift a small apple (with a mass of approximately 100 g) vertically through one metre of air.
the energy released when that same apple falls one metre to the ground.
the energy required to accelerate a 1 kg mass at 1 m·s−2 through a 1 m distance in space.
the heat required to raise the temperature of 1 g of water by 0.24 K.
the typical energy released as heat by a person at rest every 1/60 second (approximately 17 ms).
the kinetic energy of a 50 kg human moving very slowly (0.2 m/s or 0.72 km/h).
the kinetic energy of a 56 g tennis ball moving at 6 m/s (22 km/h).
the kinetic energy of an object with mass 1 kg moving at √2 ≈ 1.4 m/s.
The amount of electricity required to light a 1 watt LED for 1 s.
