Heat is transfer from one place to another due to different factors.Transmission of heat is very essential on the study of physics.
Heat is transferred from one place to another by three distinct processes:
Conduction:
Conduction is the process in which heat is transferred from a place of higher temperature to a place of low temperature by the aid of particles of the body without their mi

Specific Heat :
Specific heat of a substance is the quantity of heat required to raise the temperature of unit mass of substance through 1°C. Its unit is cal/ g° C or kilo cal/g°C.

Acceleration due to gravity :
Earth attracts all bodies towards its centre. The acceleration produced in the body due to attraction force of earth on it is called the acceleration due to gravity. It is denoted by ‘g’.
Newton’s Law of Gravitation :
According to this law any two particles in the u

Work:
The work done by a force acting on the body is defined as the product of the force and the displacement of the body in the direction of the force.
Constant Force :
If the force is constant and it displaces the body through a distance (s) in the same direction, then work done.

Friction :
When we try to slide a body on a surface, the motion of the body is opposed by a force called the force of friction. The frictional force arises due to intermolecular interaction.
When a body is at rest on a surface and no external force

Newton’s First law : The law of inertia :
It states that every body continues to be in its state of rest or uniform motion in a straight line unless some external unb

Uniform Circular motion.
When a particle moves along a circular path with uniform speed, the
motion of the particle is said to be uniform circular motion.

Physics is possible only with the help of mathematics. We need to do a lot of mathematical calculation in Physics.
Mathematics simplifies and helps in solving the problems in physics.
Thus here are some Important mathematics formulas that are needed in physics to solve and simplify any problem:
So Mathematical formulas for physics are:

If we multiply a vector with any other vector or scalar quantity then the result is called vector product.
Multiplying a vector by a scalar:
If we multiply a vector by a scalar , then the result is a new vector.
The magnitude of the vector formed by multiplying and , is the magnitude of multiplied by and the direction of the vector is same as vector if is positive an

For a simpler and more practical way of adding two or more vectors then we can use component method of vector sum or add vectors by components.
