Detailed explanation-1: - p = F net t . F net t F net t is known as impulse and this equation is known as the impulse-momentum theorem. From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum.
Detailed explanation-2: -The impulse acting on an object is equal to the change in linear momentum of that object. The dimensions of linear momentum and change in linear momentum are the same. Hence, the dimensions of impulse will be the same as that of the momentum.
Detailed explanation-3: -p = mv is the equation of momentum of a body which is equal to the product of its mass and velocity.
Detailed explanation-4: -Impulse and momentum have the same units; when an impulse is applied to an object, the momentum of the object changes and the change of momentum is equal to the impulse.
