WORLD HISTORY

Detailed explanation-1: -Force is a measure of the change of momentum over time. It can be written as F = mass x change in velocity / time. In practical terms, the momentum of an object increases when a force is acting upon it, because the force is causing it to accelerate, and to have an increase in velocity.

Detailed explanation-2: -Force (F) is equal to the change in momentum (P) over the change in time (t). And the change in momentum (P) is also equal to the impulse (J). Impulse has the same units as momentum (kg*m/s or N*s).

Detailed explanation-3: -They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt). Note that if p = mv and m is constant, then F = dp/dt = m*dv/dt = ma.

Detailed explanation-4: -Since mv is momentum, we can see that the momentum conferred to an object by a force equals the force times the time the force is applied. Thus if a 15 Newton force to the right is applied to an initially stationary object for 3 seconds, it will have a momentum of 45 kg m/s to the right.
