Common mistake
Confusing Work Done with Force
Students often confuse the concept of work done with the force applied, thinking that work done is simply the amount of force exerted.
To fix this, remember that work done is the energy transferred when a force moves an object through a distance. Use the formula W = F x s to calculate work done, where W is work done, F is force, and s is the distance moved in the direction of the force.
