Answer 2

Explanation:

A contact force is any force that requires contact to occur. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball across a room are some of the everyday examples where contact forces are at work.

Some examples for contact forces are a person throwing a ball or writing on paper. The contact forces are push, pull and friction. Some examples for non- contact forces are a magnet and a paperclip and the moon's gravity and the earth's tides.
