Question

Why do we require to apply more force to a heavy object to move it from its rest position?

Answer 1

Answer:

we know that,

Force = Mass * Displacement.

so if displacement is constant then Force varies directly with Mass. So for moving a heavy object for a particular distance more force is required than moving a non heavy object for same distance .

Answer 2

We require to apply more force to move a heavy object from its rest position because:-

1. As the mass is more gravitational pull will be more so it requires more force.

2.According to first law of motion the more the mass is the more the inertia is required to make the change in state of object.

Words to understand

*Inertia:- Property of a body due to which it resists a change in state whether it may be from rest to motion or vice-versa.
