Question

if we push the Box with a small force the box does not move why

Answer 1

that is because the friction is greater then the muscular force and for movement there should be higher muscular force as compare to friction and other forces

Answer 2

heya,

it is because the box is heavier that the force.
for moving a box we have to use our full of energy because it is heavier.

e.g
for moving a football we just have to kick it. if we use full of energy than it can hurt our toe. but if we kick it lightly than it will not go very away. it will move and stop.

thank you i hope this will helps you.
