A force of 75 N is exerted on a 45 kg sofa, and the sofa ismoved 5 m. How much work is done moving the sofa? |
Answer» Given:-
To Find:-
Solution:-The work done by a force acting on the object is equal to the product of force and displacement of the object in the direction of force. ⟹ Work done = Force × Displacement ⟹ W = Fd Put the value which is given above we get, ⟹ W = 75×5 ⟹ W = 375 JOULE. ∴ The work is done moving the sofa is 375 J. More Information!!!✧ Product of mass and acceleration is CALLED force. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀OR A push or pull of an object is called force. ✧ SI unit of Force is Newton. ✧ It is denoted by N. ✧ Force is vector QUANTITY i.e., both Magnitude and direction. ✧ SI unit of work done is Joule. ✧ Mathematical term ⟹ Force = Mass×Acceleration |
