What is the unit of work ,force and displacement in SI
system?
Answers
In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. In other words, The Joule is the unit of work.
Answer:
Work :- newton metre
Force:- newton
Displacement:- metre
Explanation:
As we know that displacement and distance are both measured in metre (m), a it is a fundamental unit.
But,
Force = Mass X Acceleration
= Mass X velocity/time
= momentum/time
= Which is also called as Force by Newton's 2nd law.(Hope you know this)
Force unit newton is named after Sir Isaacs Newton.
From both these information
Work = Force X displacement
= Newton X metre
= Joule
= same unit as Energy.
You can also verify it by the use of Dimensional analysis.
Thankyou.
