Another way of saying how much energy is transferred Work done = force x distance What's 'Work done' and 'energy' measured in? Example 3: (a) How much work is done by a horizontal force of 150N that acts on a crate for a distance of 10m? (b)How much work is done on the crate across the frictionless surface? Here is the equation that relates work done, force applied, and distance moved in the direction of the force: In the example above, 10 N is applied to move the box 2 m. The triangle above may help you to rearrange the equation. Work Done Work is done when charge flows in a circuit. We need to use the value for time in seconds (which we have just calculated).
