Question

when we try to push a very heavy box kept on ground , it does not move at all. which force is preventing this box to move forward? where does this force act?

Answer 1

Frictional Force is acting on the box preventing it to move forward

This force is equal and acting on the opposite direction of the box

This frictional Force in opposite direction is negative

To move the box the force acted by us should be more than firctional Force to overcome this force

Please mark it as brainliest answer

Hope you have understood the concept

Answer 2

It's gravitational force. This force is acting in the direction opposite to force.
