Muscular force is the force exerted on a body due to the contraction of muscles, while normal force is the perpendicular force exerted by a surface in response to an object's weight. When pushing or pulling an object, the force applied by the hand is considered muscular force, while the normal force acts between the hand and the surface of contact. The relationship between these forces can be described using the equation for contact force, which combines normal force and frictional force. Understanding the distinction between these forces is crucial for analyzing physical interactions. Clarifying these concepts can enhance comprehension of biomechanics and physics principles.

TL;DR
I am so much confused between normal and muscular force . The question I want to ask is that if I push or pull a body the force I am applying on the body is muscular force or normal force between my hand and block surface of contact??


OR, should I say that there is only muscular force acting between my hand and block surface??

Also ,according to my book it states that whenever there is a contact between two bodies there exists a contact force which is =√N²+f².
Please anyone help.

A force which exerted on a body due to muscles

The muscles act internally. They don't affect the external physics directly, but are part of the internal biomechanics of your body.
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
