how much work is done if a force of 20n is used to move an object 6 metres?

The work done is 120 joules.

Quick Scoop

To solve “how much work is done if a force of 20 N is used to move an object 6 metres?”, use the basic work formula from physics:
W=F×dW=F\times dW=F×d, where WWW is work, FFF is force, and ddd is displacement in the same direction as the force.

• Here, F=20 NF=20\text{ N}F=20 N and d=6 md=6\text{ m}d=6 m.

• So, W=20×6=120 JW=20\times 6=120\text{ J}W=20×6=120 J.

Mini breakdown

• Work is a measure of energy transferred when a force moves an object over a distance.

• The unit “joule” (J) is equal to one newton-metre, meaning 1 J is the work done by a 1 N force moving something 1 m.

• In this example, a constant force and straight-line motion make the calculation straightforward, with no angles or extra effects to consider.

TL;DR: A 20 N force moving an object 6 m does 120 J of work.
