gravity adds to your ______ when driving downhill.\ngas consumption\nbraking power\nweight\nmomentum
Answer
Brief Explanations:
Gravity causes an increase in the speed of an object moving downhill. Momentum is mass times velocity (p = mv). As velocity increases due to gravity while mass remains constant, momentum increases. Gas - consumption is related to engine operation and not directly added by gravity. Braking power is a function of the braking system and not added by gravity. Weight is the force due to gravity acting on mass and doesn't increase further due to driving downhill.
Answer:
D. momentum
