Impulse is defined as the product of which two factors?

Impulse is defined mathematically as the product of force and the time duration during which the force acts. This relationship is expressed in the impulse-momentum theorem, which states that impulse is equal to the change in momentum of an object. Therefore, when a force is applied to an object over a certain period of time, it results in a change in the object's momentum.

In this context, force represents the strength of the interaction that causes a change in motion, while time indicates the duration over which that force is applied. The greater the force or the longer the time, the more significant the impulse delivered to the object.

Other options focus on different physical relationships that do not directly define impulse. For instance, force and distance relate to work done, while mass and acceleration pertain to Newton's second law of motion. Velocity and time also do not constitute impulse; they contribute to different equations within the realm of mechanics. Thus, the correct pairing that defines impulse is indeed force and time.
