Work done by constant force

A force of \(45\,\text{N}\) moves a load \(7\,\text{m}\) in the direction of the force during a robot trolley lab. Calculate the work done. Identify the force, momentum, or energy relationship before entering the result. Enter the numerical result and choose the interpretation that matches the mechanics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
