Question

If you push horizontally on a crate and it slides across the floor, slightly increasing speed, how does the friction acting on the crate compare with your push?

Answer 1

Explanation:

If we push a crate and it slides with increasing speed i.e. there is a net force acting on the crate.

While friction always tries to oppose the motion therefore it will act opposite to the direction of applied force.

As the block is accelerating so applied force is greater than friction force. Moreover, kinetic friction is acting on the crate because the car is moving.
