Final answer:
Work and power are scalar quantities, meaning they only have magnitude, while impulse is a vector, having both magnitude and direction.
Step-by-step explanation:
The concepts of work, power, and impulse are indeed related to the transfer of momentum and energy. However, when distinguishing between scalar and vector quantities, it's essential to recognize that both work and power are scalars, meaning they have magnitude but no specific direction. On the other hand, impulse, which is the product of force and the time over which it acts, is a vector because it has both magnitude and direction, aligned with the force applied.
