Question

Write the definition of Muscular force and Friction force.​

Answer 1

Answer:

It is a force that results because of the action of muscles and is a contact force since there is contact between the surfaces. Muscular force is required whenever the movement of the body occurs

friction force:Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching

Answer 2

$\bf Muscular \: Force$

Force exerted by the muscles of a human or animal body is called muscular force. For example, when you kick a football, you apply force with the muscles of your leg. When you lift your school bag, you apply force using the muscles of your arms and you can feel the strain on your arm muscles as you lift the bag. A camel uses muscular force to pull a cart. Since muscular force can be applied to an object only when our body is in contact with the object, therefore, muscular force is a contact force.

$\bf Frictional \: Force$

Frictional Force The force acting between two surfaces in contact which opposes the motion of one body over the other is called the force of friction or simply frictional force. For example, a ball rolling down the floor slows down and finally stops on its own. A train running on the platform eventually comes to rest after applying brakes.
