Select work energy, distance, or force as the unknown, then enter the two known values. Convert between joules, kilojoules, calories, meters, feet, newtons, and lbf.

Work divided by a positive distance gives the constant or distance-averaged force component along motion. Negative work gives an opposing component.

Energy To Force Formula

The following equation is used to calculate the Energy To Force.

F = E / d
  • Where F is the force (N)
  • E is the energy (joules)
  • d is the distance (m)

To calculate the force component along motion, divide the energy transferred as work by a positive distance. This gives a constant component, or its distance average when it varies. For a constant angled force, the component is F cos θ.

Force is calculated using F = E / d (E in joules, d in meters). 1 N ≈ 0.224809 lbf (1 lbf ≈ 4.44822 N).

Can Energy be Converted to Force?

Definition:

Work is energy transferred by a force through displacement. Energy alone does not specify force: the distance and force direction also matter. The relation E = Fd here uses the component along motion; negative work corresponds to an opposing component.

How to Convert Energy to Force?

Example Problem:

The following example outlines the steps and information needed to calculate force from energy.

First, determine the total amount of energy. In this example problem, the total amount of energy is 500 joules.

Next, determine the distance over which the force acted on the object. In this case, the distance is 5 m.

Finally, calculate the force using the formula above:

F = E/d

F = 500/5

F = 100 N
