Question

How is Joule defined?

Answer 1

Joule is the unit of energy in the International System of Units (SI). It is named after the physicist James Prescott Joule. One joule is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter in the direction of the force. In other words, it is the work done when one watt of power is applied for one second.

If you want to calculate the joules for a given situation, you need to know the force applied and the distance over which it is applied. The formula to calculate joules is:

Energy (in joules) = Force (in newtons) x Distance (in meters)

For example, if a force of 10 newtons is applied over a distance of 5 meters, the energy transferred would be:

Energy = 10 N x 5 m = 50 joules

Answer 2

Joule is the SI unit of energy and work. It is defined as the amount of work done by a one newton force acting over one meter distance. In terms of equations, one joule is equal to one newton-meter (1 J = 1 Nm).

Answer 3

How is Joule defined?

Joule is the SI unit of energy and work. It is defined as the amount of work done by a one newton force acting over one meter distance. In terms of equations, one joule is equal to one newton-meter (1 J = 1 Nm).

Joule is defined as the SI unit of energy, equal to the work done when a force of one newton is applied over a distance of one meter.
