Question

State newton second law established the relationship between force and momentum of a body

Answer 1

The second law states that the rate of change of momentum of a body is directly proportional to the force applied, and this change in momentum takes place in the direction of the applied force. ... In other words, if a body is accelerating, then there is a force on it.

Answer 2

Newton's second law states that the rate of change of momentum of a body is directly proportional to the external force applied on it...

$\frac{dp}{dt} = f \\ \frac{mdv}{dt } = f \\ ma = f$
