Question

difference between friction force and muscle force

Answer 1

Answer:

Friction force is the force which resists the force of solid surfaces, as well as fluid layers and all kinds of material elements which are constantly sliding against each other.

On the other hand, muscle force is brought about by human agency, which is of far lesser magnitude than friction force.

Answer 2

"Muscular force:

• This force does not produce heat when work is done.
• It is under our control which is used when we lift an object with the help of muscles.
• It cannot be used anywhere as it needs our muscles.

Friction force:

• This force produces heat when work is done.
• It is under the control of the object and surface.
• It can be used anywhere with any of the objects."
