What is the formula for calculating force in relation to momentum?

The formula for calculating force in relation to momentum is derived from Newton's second law of motion and the definition of momentum. Momentum is defined as the product of an object's mass and its velocity, and when a force is applied to an object, it causes a change in momentum over time.

In this context, the correct formulation states that force is equal to the change in momentum divided by the change in time. This is proven by rearranging the equation that links force, mass, and acceleration (F = ma). Acceleration can be defined as the change in velocity over time, and when multiplied by mass, which results in a change in momentum (since momentum p = mv), it leads to the relationship:

Force = Change in momentum / Change in time.

This relationship highlights how a net force acting on an object results in a change in its momentum over a specific time interval, emphasizing the direct connection between force and momentum. Thus, the correct answer reflects the fundamental principles of how forces influence motion in the field of physics.
