A spring balance can be used to measure

A) Mass of an object

B) Force acting on an object

C) Density of an object

D) Weight of an object

Four children were asked to arrange forces due to rolling, static and sliding frictions in a decreasing order. The correct arrangement is :

A big wooden box is being pushed on the ground from east to west direction. The force of friction due to ground will act on this box towards:

The friction between two surfaces does not depend on one of the following. This one is:

If the sliding friction between two surfaces is found to be 8 N, then the static friction between these two surfaces is most likely to be:
