Answers
Answer:
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction.
Answer:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
The factor affecting friction are:1. The weight of the object. 2. The type of contact between the two surfaces.
EXAMPLES
Friction is what holds your shoe to the ground. The friction present on the ice is very little, this is the reason why it is hard to walk on the slippery surface of the ice. Writing – A frictional force is created when the tip of the pen comes in contact with the surface of the paper. ... Water lowers friction.
