Newtons Second Law Formula

Newton’s second law of motion is formally stated as The acceleration of an object generated by a net force is directly proportional to its magnitude and in the same direction as the net force and inversely proportional to the mass of the object.

Newton’s second law is among the most important laws of motion in Physics, under the study of forces and matter. It describes the relationship between mass and acceleration of a body towards the force.

According to Newton’s second law, the force is expressed by the product of mass and acceleration of the body.   

Newton’s second law Formula is given by,

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 values are,

m = 5kg and

a = 10m/s

Newton’s second law Formula is given by,

F = ma

  = 5 ×10

  = 50N

Example 2

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

Solution:

Given values are,

m = 6kg and

a = 30m/s

Newton’s second law Formula is given by,

F = ma

  = 6 × 30

  = 180N
