 # Newtons Second Law Formula

Newton’s second law of motion is officially specified as the net force generated by an acceleration of a body is directly proportional to the magnitude and inversely proportional to the body mass. The magnitude will be in the same direction as the net force obtained by the body due to its acceleration.

In Physics, Newton’s second law of motion is a very important law in order to study the matter and force. It gives the relationship between the mass and acceleration of the object in terms of force.

According to the law, force is equal to the product of acceleration and mass of the object.

The formula for Newton’s second law is

F = m a

Wherein,

m = mass

a = acceleration

Example 1

Determine the applied force of an object of 5kg moving with a velocity of 10m/s?

Solution:

Given

m = 5kg and

a = 10m/s

Newton’s second law Formula is given by,

F = ma

F = 5 ×10

F  = 50N

Example 2

An object of 6kg is moving with a velocity of 30m/s. Determine its force.

Solution:

Given

m = 6kg and

a = 30m/s

Newton’s second law Formula is given by,

F = ma

F = 6 × 30

F = 180N
