Work done by a force is given as the product of force and the distance moved by the force.
<h3>What is work done?</h3>
Work done is the product of force and the distance moved by the the force.
- Work done = Force × distance
Thus, distance required by the 100 N force is given as:
- Distance = work done/force
Distance = 1000/100 = 10 m
Distance to be moved is 10 m.
Force applied = work done/ distance
Force applied by the hoist = 500/2
Force applied by the hoist = 250 N
Distance moved in one push-up = 25 cm = 0.25 m
Work done by the athlete after one push-up = 250 × 0.25 m
Work done by the athlete = 62.5 J
Distance moved by the force = 0 m
Work done = 500 × 0 = 0 N
Therefore, for work to be done, force has to move a distance.
