A force of 20N causes a displament of 1.5M in an object in ist own direction calculate the work done by force?
Answers
Given:
Force :- 20N
Displacement :- 1.5M
To find:
Work done by force.
Solution:
We know,
Force is 20N that causes 1.5M displacement.
Concept:
☞ The push or pull of an object is called Force.
☞ The shortest distance travelled by an object between initial position to final position is called Displacement.
☞ In question, a object of 20N causes a 1.5m of displacement in an object in its own direction.
☞ We have to find work done, Work is said to be done when a force produces a displacement in the body and acts in any direction except perpendicular to the direction of displacement.
Work = Force × Displacement
Calculation:
➡W ≈ F × D
➡W ≈ 20 × 1.5
➡W = 30 Joules
Note: SI unit of work done is joule, so ans always written in joule.
F means force=20N
D means displacement=1.5m
W=FXD
20 X 1.5
=30joule ans
