During a picnic, Quinton places a ball on a slope and lets go. There is no external obstruction in the ball's path. What happens to the ball, and why?
Make your response very short.
The ball rolls down the slope due to gravity. Gravity pulls objects toward the center of the Earth, and when an object like a ball is placed on a slope, it causes the ball to move in the direction where the slope descends. The steeper the slope, the faster the ball will accelerate down it.
