2. A brick can be pushed gently on a smooth floor by applying a force with our foot. But if we
kick the brick, the foot is hurt why?​

Answer 1

Answer:

1)We are able to walk due to the force of friction. Friction is a contact force and arises when two objects are in direct contact with each other. ... When we step on a banana peel, the friction force between the feet and the peel decreases and we are not able to move forward and slip.

Explanation:

2)brick can be pushed gently on the smooth floor by applying force with our foot. But if we kick the brick, the foot is hurt. ... Therefore, rate of change of momentum of the brick is large. So, a large reaction force is applied back by the brick on the foot.
