Question

Define -1 Frictional force
2. Muscular force
3. Magnetic force ​

Answer 1

1) Frictional force:-Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in the contact.

2) Muscular force:-Muscular force is the force applied using parts of the body like arms or legs. It is force that results due to the action of muscles, and is a contact force, since there is a contact between the surfaces. Muscular force is needed whenever movement of the body occurs.

3) Magnetic force:-Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

Answer 2

Answer:

1)

Frictional force refers to the force generated by two surfaces that contacts and slide against each other.

2)The force exerted by the action of our muscles is known as muscular force

3)Magnetic force refers to attraction or repulsion that arises between electrically charged particles because of their motion.
