Question

the following picture and name the forces exerted also state whether they are contact on non contact​

Answer 1

$\huge\bold\red{Answer}$

° The forces which act on bodies when they are in physical contact. are called contact forces. For e.g. frictional force and force exerted on two bodies during a collision.

° The forces experienced by bodies even without being physically touched are called the non-contact forces. For e.g. Gravitational force and Electrostatic force.

Contact force : -

• (a) frictional force
• (b) normal reaction force
• (c) force of tension in a string

Non-contact force : -

• (d) gravitational force
• (e) electric force
• (f) magnetic force
