Final answer:
The statement that impulse equals the change in an object's momentum is true, as per the Impulse-Momentum Theorem, which states that impulse (J = FnetΔt) results in a change in momentum (Δp), and these two values are equal.
Step-by-step explanation:
The statement that impulse is equal to the change in the momentum of the object that the impulse acts on is True. According to the Impulse-Momentum Theorem, an impulse applied to a system changes the system's momentum, and that change of momentum is exactly equal to the impulse that was applied, which can be mathematically expressed as J = Δp.
Impulse is defined as the product of the average net external force (Fnet) applied to an object and the time interval (Δt) over which it acts, given by the formula J = FnetΔt. This impulse results in a change in the object's momentum (Δp), which is the difference between the object's final momentum and its initial momentum.
If no external forces act on the system, the total momentum of the system remains constant due to the Conservation of Momentum. Therefore, the impulse received by an object is always equal to its change in momentum, regardless of whether the forces are constant or vary over the given time interval.
