Title: Class 8 physics Numerical Problem
Question:
A force of 30N acts on a body and moves it through a distance of 5m in the direction of force.
Calculate the work done by the force ?
Answer:
Given :
Force F = 30 N
distance d = 5m
Work done = ?
Formula:
Work done W = F×d
Substitute the value
W = 30N × 5m
=150Nm
Unit Conversion:
1 Nm =1 Joule ( J )
So,
W = 150 J
Final Answer:
Work done = 150 J
