Newton's Second law of motion states that equation below:

Sum of F = ma where Sum of F is the total external force acting on the body, m is the mass and a is the acceleration of the body. Describe Newton's second law in terms of change in the momentum.

1) The sum of all external forces acting on the object is equal to the object's change in momentum

2) The sum of all external forces acting on the object is equal to the rate of change in the momentum of the object

3) The sum of all external forces acting on the object is equal to the object's impluse

4) The sum of all external forces acting on the object is equal to the inverse of the object's impluse
