Question

it is easier to push a lighter box than a similar heavy box on the same floor. Give reasons

Answer 1

because frictional force will be more in the case of heavy box so it is difficult to move heavy box than a light box

Answer 2

Because the frictional force can be easily overtaken when we push a lighter box but it is not easy in the case of a heavier box as it has a higher mass and the frictional force will be strong on it untill pushed with great force
