Question

Define Newton’s 2nd law of motion​

Answer 1

Explanation:

Newton's 2nd Law of Motion

The rate of change of momentum is directly proportional to the applied force and it takes place in the direction of the applied force.

rate of change of momentum = m(v - u)/t

F ∝ m(v - u)/t

we know that v - u / t = a

putting a in the equation

F ∝ ma

therefore F = kma

If we consider unit force is acting on unit mass with unit acceleration.

then F = 1, m = 1, a = 1

so, k = 1

Hence, F = ma.

Answer 2

Answer:

Newton's Second law of motion.

According to Newton's second law of motion the rate of change of momentum of a body is directly proportional to the force applied on it and the change in momentum takes place in the direction in which the force is applied.
