Want this question answered?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
According to Newton's second law, the rate of change of momentum of an object is directly proportional to the net force that is acting on that object.
A change in the velocity is produced by a force acting on the object. A change in velocity means a change in speed or direction (or both).
The system wherein the net momentum is zero at all times during the stone's fall is the stone itself. Momentum is a vector quantity, and the stone experiences an equal and opposite change in momentum at each instant due to the gravitational force. The external forces acting on the stone can be neglected in this case.

A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
use the Impulse-Momentum theorem where (Fnewtons)(tseconds)=change in momentum change in momentum=Pf-Pi; P=mv
In that case, the object's rotational momentum won't change.
impulse is equal to force which is acting on the body and ti me in small interval which is equal to momentum.so impulse is equal to change in momentum and direction of impulse is consider the direction of force and change in momentum.
In order to impart the greatest momentum to an object, you should both exert the largest force possible upon the object in question and extend that force for as long as possible. This is so because the greater the force acting on an object results in a greater change in velocity, which in turn yields a greater momentum. In addition to exerting the largest force possible on an object, you should also extend that force over the longest period of time as possible, as the sustained force also produces more momentum. As p= m•v, the best method in obtaining the greatest amount for 'p' would be to manipulate either the 'm' or 'v' variables. Force= acceleration= change in velocity= MOMENTUM. Greater amount of time= MOMENTUM
Yes, that's a true statement.

IN general change is defined as the difference of initial from the final. So change = Final - Initial. Hence change in momentum = Final momentum - initial momentum
Impulse is change in momentum. Refer to the related link for more information and equations concerning change in momentum.
