Newton’s Second Law

All of us have seen the equation Force= [mass] [acceleration] in high school. This is a form of the Newton’s second law of motion. This a quantitative law whereas the first law is a qualitative law. But first let us understand what Force is. Physically, Force is a Push or Pull. Its mathematical representation is given by, Force is the rate of change of Linear Momentum. This rate of change of linear momentum is what we know as mass times acceleration.

Now let us look at the units of force. The S.I. unit of force is Newton. It is kept so in the honor of Isaac Newton. The dimensions of force are [M1 L1 T-2]. This kilogram-meter per second squared is what we all call Newton. Thus a unit force is 1 Newton. Newton in short is also written as- “N”. Thus when we say that a block experiences a force of let’s say 5 newton we can represent it as F=5N.

Well that is all about Newton’s Second Law of Motion. If you are interested in further knowing about this law please visit the link at the end of this small article. Thanks for reading!
