Newton's Second Law

Newton's Second Law or Newton's second law of motion is probably the most famous of all of Newton's three laws of motion. Newton's second law of motion introduces one of the most famous mathematical or physics formula concerning mass, force and motion. So, what is this Newton's Second Law of Motion?

Formula for Newton's Second Law of Motion

Newtons Second Law of Motion

Newton's 2nd law of motion states that if an object of mass m which is measured in kilograms is acted on by a force of magnitude F measured in Newtons, the magnitude of the acceleration a (measured in meters per second squared) can be found according to the physics formula F equals m times a or Force is Mass times Acceleration.

Unit of force

Force is measured in Newton which is the standard unit of mechanical force. The unit Newton is often written as capital N. What does one Newton of force mean? One Newton (N) of force is the force that it takes to make a mass of 1 kilogram accelerate at a rate of 1 meter per second squared. Since Force is mass multiplied by acceleration, the Newton is really kilogram, meter per second squared. But, all you really need to remember is that Force is measured in Newton.

Newton's Second Law formula

That's it. Newton's 2nd Law of Motion is given by F equals m times a or mass times acceleration measured in Newton.
