Answer 2

Answer:

a. Contact force.

Explanation:

• a contact force is any force that requires contact to occur.
• contact forces are ubiquitous and responsible for most visible interactions between macrosscopic 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.
• the forces which act on bodies when they are in physical contact.
• are called contact forces.
• fo example: frictional force and force exerted on two bodies during a collision.
• contact force occurs due to the contact between two different objects.
• non-contact force occurs due toeither attraction or repulsion between two objects such that there is no contact between these objects.
