Answer 1

Answer:

1.For example :- Muscular Forces, Frictional Forces, are the Examples of contact Forces.

Cycling, pushing and pulling the drawer of a table , kicking a ball , etc. are some other examples of contact Forces.

2.Your answer is yes,

Your answer is yes,eg.Frictional force between book and table

Your answer is yes,eg.Frictional force between book and tableand

Your answer is yes,eg.Frictional force between book and tableandGravitational force between earth and every object near it.

Hey mate, here's your answer

• Examples of contact forces are pushing a car up a hill, kicking a ball, pushing desk etc.

• Yes non living object s can exert force. eg, frictional force between book and a table or gravitational force between earth and every object present on earth.

• Law of inertia is a law formulated by Issac Newton which states than a body in rest remains to be in rest position and a body in motion tends to be in motion until an external force is applied to it.
