Question

the work done on an object does not depend upon the option number a displacement option number be initial velocity of the object option number c force applied option number d angle between the force and the displacement MCQ in one mark class 9 it is very urgent and important to me ​

Answer 1

Answer:Work done does not depend upon the initial velocity of the object

W=FscosФ

whereФ= angle between force and displacement

F= force applied on the object

s= displacement of the object

IfФ=90° then no work is said to be done

If Ф>90° negative work is done

If Ф<90° positive work is done
