Answer 2

Answer:

Explanation:

Muscular force is the force that is applied by using our muscles ( as we know that our body has muscles )

Example : doing agricultural works , weight lifting , writing etc .

Frictional force is the force that is applied between two objects that are in same direction .

Example : while rubbing two magnets , tubing our hands etc .
