    W=F×s So to do work we have to apply force on object and by this force object should be displaced in the direction of force

    1Thank You

    Aditi Jadhav 3 years, 6 months ago

    Q. A force of 7 N acts on an object. The displacement is, say 8m, in the direction of the force. Let us take it that the force acts on the object through the displacement. What is the work done in this case? F=7N S=8m W=? W=F×S W=7×8 W=56

    Mass 1. Mass is the quantity of matter in a body regardless of its volume or of any forces acting on it. 2. Mass is an absolute quantity and is a measure of inertia.  Inertia 1. Inertia is a tendency of an object to continueits state of rest or motion. 2. It is the resistance of an object to change its state of motion. 3. Inertia depends on mass. Larger the mass, larger the inertia
