Physics Basic Concepts

Today we will study about force.
Definition of Force:
Force is a push or a pull effort that one object exerts on another object.

SYMBOL:
Force is denoted by 'F'.

MATHEMATICAL EXPRESSION:
F= ma

From above formula we can also define force .
"The product of mass and acceleration is known as force."

UNITS:
Unit of force is 'Newton'.

DIMENSION:
Dimension of force is LMT^-2

:
The product of mass and velocity of an object is called momentum.
It is a three dimensional vector quantity, possesssing direction and magnitude.
:
It is denoted by P.

:

If m is mass and v is velocity of an object then its momentum will be:
P=mv
