Question

Match the most suitable pairs:

• A. Negligible friction
• B. Kinetic friction
• C. No friction

Answer 1

Due to the smooth surface, ice offers very less friction which is almost negligible. When riding a bicycle, the tyres of the cycle are moving on the ground and hence kinetic friction exists.
And when we are resting on a chair, since we are not moving and neither we are trying to move there is no friction acting on our body.
