If Kofi is standing at the base of a hill and looks up to the top where his friend Priya is standing with a ball, what will Kofi see when Priya lets go of the ball? Provide a very brief response.
Kofi will see the ball roll down the hill toward him. Gravity pulls everything toward the center of the Earth, so when Priya releases the ball at the top of the hill, it will naturally be pulled downwards. Since the ball is on a slope and is no longer being held in place, it will accelerate down the hill following the direction of the slope. Kofi, standing at the bottom, will observe the ball rolling downward from Priya's position towards his own due to gravity.
