What is Newton’s Second Law of Motion in Physics
Newton’s Second Law of Motion
The acceleration of a body, “a” is directly proportional to the net force acting upon it F, and inversely proportional to its Mass “m”.
Derivation
According To The Newton‘s Second law of motion when a force acts on an object it produces an acceleration which is directly proportion to the amount of the force,
So, F = ma
Where:
F = force [N]
M= mass [kg]
A = acceleration caused by F [mS-2]
- Force
Changes the size, shape, state of rest, velocity and/or direction of an object
Force is a vector quantity.
- Mass
The quantity of matter contained in a body is called mass.
Formula
F = ma
m = F/a
Unit:
The unit of mass in M.K.S system is Kilogram (kg)
Note: In the process of training students undergo introductory, industrial and pre-diploma practice in agricultural holdings, agricultural enterprises, government institutions, banking structures, industrial enterprises, as well as in training firms. The full-time students have the opportunity to study in parallel in 2 directions at the Kazan State University, or to master the working professions in addition, to participate in foreign internships under international programs. Only full-time education gives students an idea of the real eventful student life. Extra-curricular work with students opens up huge opportunities for young people to realize their creative potential (classes in a scientific student society, participation in student self-government – work in the student council, newspaper publication, theater, competitions, holidays and much more).
