A 70 n force pulls a box straight up 5 m above the ground. how much work is done on the box?
lord [1]

The work done on the box is 350 joules

Workdone can be described as the amount of energy transferred from an object.

Force can be described as the push on an object, this push makes the object to go through a change in velocity.

Distance can be described as the movement of an object towards any given direction.

It can be calculated by multiplying the force by the distance

Workdone= force × distance

= 70 × 5

= 350

Thus, the work done on the box is 350 joules
