... mass of an object times its velocity. Impulse is equal to the force on an object times the amount of time that the force was applied to the object. The impulse momentum theorem equates impulse to momentum (FΔt = mΔv). Conservation of momentum requires that the momentum of a system before a collision ...

This causes the resultant force to decrease and so the object’s acceleration decreases (shown by the fact that the gradient of the velocity-time graph decreases). Eventually, when the terminal velocity is reached, the dr ...
