Answer :

If there is a hill, it will move more slowly. It will continue moving at the same speed if the surface is flat. Gravity is what causes a slope’s change in speed.

Things move more quickly when moving downhill and more slowly when moving upwards (slow down).

If an object’s speed is constant, can it accelerate?

Yes, many individuals initially find this counter-intuitive because they overlook the fact that acceleration can still occur even when an object maintains a constant speed.

What forces are at work when an automobile is climbing a hill?

The force that is sent up the hill is powered by the car’s engine. Because the engine makes the drive wheels rotate, the road applies this force, which is actually static friction, to the drive wheels.
