Question

define static friction

Answer 1

The force of friction experienced by a body before it starts sliding on the other surface is called static friction.

Answer 2

Static friction is the friction that exists between a stationary object and the surface on which it's resting.Have you ever noticed that it's harder to get a shopping cart moving than it is to keep it moving? If you try to push your couch across the room, the first push is the hardest part. Maybe people assume that's nothing more than psychological, but there really is a physics reason for it. The reason is static friction.
