Question

1. How much work is done on a 20-N rock that you lift 1.5 meters up?

A) 3 Joules
B) 30 Joules
C) 3 Watts
D) 30 Watts

Answer 1

= 30 joules

Explanation:

Work done is given by the product of Force and distance

Work done = Force × distance

Work is measured in joules.

Force = 20 N , distance = 1.5 m

Thus;

Work done = 20 N × 1.5 m

= 30 Joules
