What does momentum depend on in physics?

Momentum is a fundamental concept in physics that is defined as the product of an object's mass and its velocity. This relationship can be expressed mathematically as momentum equals mass multiplied by velocity (p = mv). Given this understanding, let's clarify why the option regarding the change in force over change in time is pertinent to the concept of momentum.

Change in force over change in time refers to the concept of impulse, which relates to momentum through Newton's second law of motion. Impulse is defined as the change in momentum of an object when a force is applied over a period of time. Therefore, when a net external force acts on an object, it changes its momentum proportionally to the amount of force applied and the duration of time the force is applied. This principle indicates how forces influence the momentum of objects.

While momentum is fundamentally dependent on both the mass and velocity of an object, the idea of change in force over time emphasizes the dynamical aspects of momentum. It underscores how forces cause changes to momentum, illustrating the relationship between force, time, and the resultant change in an object's motion.

The other options do not encompass the full scope of what momentum depends on. Mass of an object only and speed of an object only, while important factors, do
