Newton's Second Law of Motion

Newton's Second law of motion is very important specially relating to the calculations involving force and motion. This is the basic law relating the force applied on an object and the resultant acceleration gained by that object. So, this law has become a basis of many theories and laws proposed in the Physics.

This law states that:

Force applied on a object is directly proportional to the
acceleration acquired by it.

Putting constant k along with mass m, we get:

Now, value of k has been found to be 1 in SI units. Putting this value in the above equation, we get:
