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