Question

When a heavy box is pushed ,it does not move because of
A) Static friction
B) Sliding friction
D) Fluid friction
C) Rolling friction​

Answer 1

Answer:

A) Static friction

Static friction is a force that keeps an object at rest. It is the friction between 2 or more solid objects.

It is defined as: The friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface which it is on.

So when a heavy box is pushed, friction from the ground acts in opposite direction on the object. In this case, it is Static friction.

Another example:

• Lamp on table
