Important Physics Definition

Important physics related definition in simple way 

1)Force (F): Force is nothing but it is product of mass(m) and acceleration(a)
                Force is given by  F=ma 









 2)Pressure (P): Pressure is ratio of Force(F) to the area(A) upon which it act
Pressure is given by  P=FA











3)Density: Density is ratio of mass(m) and volume(v). It is use to find how heavy an object is relative to its size.
      Density is given by   p=m/v










4)Efficiency: Efficiency is the ratio of output to the input. This output and input can be any means it may be energy ,power etc.
Efficiency is use to find how much work or energy conserved in a process.
A perfect process would have an 100% efficiency. But this is impossible in practical use.
Efficiency= Output/Input   
For getting efficiency in percentage multiply the ratio by 100

5)Potential Energy (U): It is the energy that is stored in a system.
The body have gravitational potential energy when object has been raised above the ground.It is product of mass(m), acceleration due to gravity(g) and height(g) from which object fall.
Potential energy is given by  U= mgh

6)kinetic energy (E): kinetic energy is the energy that is possess due to motion of an object.
It is product of mass(m) and square of velocity(v) of an object at which object moving.
kinetic energy is given by   E=1/2mv^2













7)Momentum (P): Momentum is the product of mass(m) and velocity(v) of an object.
momentum is given by P=mv










8)Voltage (V): Voltage is the product of current(I) and resistance(R) occure in the circuit.
Voltage is given by V=IR 

9)Work (W): Work is product of force(F) act on body and distance(D) covered by it.
Work is given by W=FD











10)Power (P): Power is product of voltage(V) and current(I) in circuit
Power is given by  P=VI
