How much energy is 500 joules?

Answer 1

In physics, energy is measured in joules (J), which is the amount of work done by a force of one newton acting over a distance of one meter. Therefore, 500 joules represents the amount of energy transferred or converted in a system. To put it into perspective, 500 joules of energy could be equivalent to lifting a 50-kilogram object to a height of 10 meters against the force of gravity.

Answer 2

500 joules is equal to 368.78 ft-lbf.

For example, an object has 500 joules of kinetic energy, when its mass is 10 kg (~22 lbs) and it is traveling at 10 m/s (36 km/h or ~38.2 ft/s).

Second example: The muzzle energy of a traveling 9mm bullet is around 500 joules.

Third example: An object with mass of 5kg (11 lbs) and which is raised at 10 metres (32.8 ft) has around 500 joules of potential energy.

So, 500 joules is quite much. Getting hit with an object which has 500 joules of kinetic energy can be lethal.

Answer 3

500 joules is a unit of energy equivalent to the work done by a force of one newton moving an object one meter against a force of one newton. It is a relatively small amount of energy, for example, if you were to lift a 5 kg object one meter off the ground, you would use about 50 joules of energy.
