Question

Consider the following three cases. You try to push on a large box that has a mass equal to your mass across the floor. However, the box does not move due to friction. How do the magnitudes of the forces between you and the box compare to each other? You switch to a box that has a mass that is half of your mass and try to push it across the floor, but it also does not move. How do the magnitudes of the forces between you and the box compare to each other? You are able to place the box that has a mass half of your own onto a platform with wheels and you are able to push the box across the floor. How do the magnitudes of the forces between you and the box compare to each other?

Explanation / Answer

1. frictional Force here is greater than the applied force, hence the body doest moved

i.e Ff/N > 1

2. here also frictional Force here is greater than the applied force, hence the body doest moved

i.e Ff/N > 1

3. Applied dforce is larger than frictional forc Ff/N <1
