A force $8 N$ causes a displacement of $4 m$ in a body in the direction of force.Calculate the work done.

Open in App

Solution

Step 1: Given
The force applied to an object = $8 N$
Displacement of the body in the direction of force = $4 m$
Step 2: Calculation
Work done $w = F \times s$
$= 8 \times 4$ = $32 J$
Hence, work done $= 32 J$ .
