NEWTON SECOND LAW OF MOTION-தமிழ்



Newton's second law of motion:
The rate of change in momentum of a body is directly proportional to the applied force on a body and takes place in the direction of the force.

Momentum:
It is the product of mass and velocity. It's unit of Kgm/s

Momentum=mass X velocity
It is to study the number of motion take place in the system.

Change in Momentum=Final momentum-Initial Momentum

Change in the momentum of a body α Applied force on a body

Force, F=ma (Newton) N

Where m= mass (Kg)
a=acceleration(m/s^2)
Acceleration:
It is defined as the ratio of the change in velocity to time. It is a vector quantity and 3-Dimensional system.



Acceleration due to gravity in earth=9.81m/s^2

CONCLUDE:

Newton's Second law of motion used to find the data or value of the acceleration and force in the system
