Explanation:
Detailed explanation-1: -The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved. Kinetic energy can be transferred between objects and transformed into other kinds of energy.
Detailed explanation-2: -Hence, The change in the momentum of an object is equal to the impulse applied to it.
Detailed explanation-3: -If a non-zero net force acts on the object, the magnitude of its momentum could decrease, increase, or remain constant. p decreasing and increasing: If the net force opposes the motion of the object, the object will slow down and its direction of motion may or may not change.
Detailed explanation-4: -Impulse is equal to the change in momentum ( p
