what is static friction?
Answers
Answer:
Static friction is the force of friction on an object that is not moving. If you push on a stationary block and it doesn't move, it is being held by static friction which is equal and opposite to your push.

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. Friction, in general, is a force that makes it harder for two objects to slide alongside one another. Static friction is the friction that exists between a stationary object and the surface on which it's resting.

Friction, in general, is a force that makes it harder for two objects to slide alongside one another. Static friction is the friction that exists between a stationary object and the surface on which it's resting.Once the objects have already started moving, kinetic friction takes over. This is the friction that exists between two objects moving relative to each other. Kinetic friction isn't as strong as static friction, and so it's easier to keep the shopping cart moving.
