Question

Gravity __________ your kinetic energy when you are driving uphill and __________ it when you are driving downhill.

1) increases, decreases
2) stops, increases
3) decreases, increases
4) none of the above

Answer 1

Gravity decreases kinetic energy when driving uphill and increases it when driving downhill. The correct answer is 3) decreases, increases.

Step-by-step explanation:

The question involves the concepts of kinetic energy and gravity's role in affecting it while driving uphill and downhill. Gravity decreases kinetic energy when you are driving uphill because gravity is opposing the motion of the car, requiring more energy to climb against the pull of gravity.

Conversely, gravity increases kinetic energy when you are driving downhill since it assists the motion of the car, adding to its speed due to the gravitational pull in the same direction as the car's motion. Therefore, the correct answer is 3) decreases, increases.
