Q What Is Muscular Force Physics
Muscular force refers to the force exerted by muscles in the legs and arms. It is also the type of force produced by the action of the body muscles, which causes it to keep in touch with the surfaces. Strolling, sitting in seats, jumping, and weight lifting seems to be muscle force instances. Another example of muscular force is bouncing back from a fall. Whenever something is touched, and then force is applied to it, this is the type of force exerted.
To put it another way, muscular force is linked to body position. There has yet to be discovered a force that can represent muscular force. People continue to believe that only a few instances of forces can constitute muscle force, for instance.
Many people assume when two magnets attract each other, it is due to muscular attraction, but this is not the case it is due to magnetic attraction. The gravity force, not just the magnetic pull, will cause the fruit to fall.
Friction produces electrical charges, which are an instance of a frictional force rather than a muscle force. Even though the human body contains over 600 muscles, there are only three types of muscles that are vital to the muscular force. Cardiac, skeletal, and smooth muscles were examples of these types of muscles.

What Is Gravitational Potential
The amount of work done in moving a unit test mass from infinity into the gravitational influence of source mass is known as gravitational potential.
Simply, it is the gravitational potential energy possessed by a unit test mass
V = U/m
- The gravitational potential at a point is always negative, V is maximum at infinity.
- The SI unit of gravitational potential is J/Kg.
- The dimensional formula is M0L2T-2.

Expression For Gravitational Potential Energy At Height Derive U = Mgh
If a body is taken from the surface of the earth to a point at a height h above the surface of the earth, then ri = R and rf = R + h then,
U = GMm
U = GMmh/R
When, h< < R, then, R + h = R and g = GM/R2.
On substituting this in the above equation we get,
Gravitational Potential Energy U = mgh
- The weight of a body at the centre of the earth is zero due to the fact that the value of g at the centre of the earth is zero.
- At a point in the gravitational field where the gravitational potential energy is zero, the gravitational field is zero.
Gravitational Potential Of A Spherical Shell
Consider a thin uniform spherical shell of the radius and mass situated in space. Now,
Case 1: If point P lies Inside the spherical shell :
As E = 0, V is a constant.
The value of gravitational potential is given by, V = -GM/R.
Case 2: If point P lies on the surface of the spherical shell :
On the surface of the earth, E = -GM/R2.
Using the relation
Gravitational Potential = -GM/R.
Case 3: If point P lies outside the spherical shell :
Outside the spherical shell, E = -GM/r2.
Using the relation
V = -GM/r.

Derivation Of Gravitational Potential Energy Equation
Consider a source mass M is placed at a point along the x-axis, initially, a test mass m is at infinity. A small amount of work done in bringing it without acceleration through a very small distance is given by
dw = Fdx
Here, F is an attractive force and the displacement is towards the negative x-axis direction so F and dx are in the same direction. Then,
dw = dx
Since the work done is stored as its potential energy U, therefore gravitational potential energy at a point which is at a distance r from the source mass is given by
U = -GMm/r
If a test mass moves from a point inside the gravitational field to the other point inside the same gravitational field of source mass, then the change in potential energy of the test mass is given by
U = GMm

Jee Books Pdf : Joint Educational & Examination Books Pdf Entrance Exams Overview
While exploring UG/PG level education, applicants are bound to come across some form of required examination or an aptitude test as being a requirement for admission. Some universities even go to the extent of indicating the sum of scores needed to make the cut off point. So what are these exams and what do they normally measure?
In most cases these tests are administered by an independent testing centre or a professional association. The main objective is to provide a common yard stick to measure the potentials of all applicants that might come from different backgrounds and curricular against a standardized set of skills that would be required by a specific program. It provides university and college admission counselors with a clear cut measure that is somewhat effective, in trying to assess the ability of candidate to join their program. There are schools that dont make these exams a requirement. But more and more schools are becoming inclined towards making them mandatory as these tests do give some indication about the applicant and therefore it is advisable to in most cases to consider taking these exams.
Entrance examinations act as qualification exams for admission to higher studies in various reputed institutions of the world. They can be of various types, actually.

What Is Force According To Physics
In simple sense, force is synonymous to push and pull between two objects that come in contact with each other. If two objects interact or collide with each other, they are said to be exerting force on each other. Force can only persist when two objects come in contact. Without any contact, there is no force present.
Forces can be contact forces or forces consequent to actions at a distance. When there is a physical interaction between two or more objects, the force exerted is known as contact forces. In contrast, when two objects are not in physical contact, the force present is force consequent to actions at a distance. Here, the force that is present is the gravitational force.
Under the contact forces, there are several other kinds of forces classified in the same category. These are frictional force, normal force, applied force, air resistance force, etc. Under the forces consequent to actions at a distance, there are classifications too. These are magnetic force, electric force and gravitational force.
Force is measured in a standard unit known as Newton. It is a vector quantity which indicates that it has both direction and magnitude. This means that force can move towards a particular direction or directions. It can range between lower, average and high magnitude, depending on how it has been exerted.
