1. Which object will experience more air resistance: a skydiver falling without a parachute or a skydiver falling with a parachute?
2.If a tennis ball, a golf ball, and a bowling ball are all dropped from the same height at the same time, which ball will hit the ground first? (Pretend that there is no air resistance on the balls.)
1. The skydiver falling without a parachute will experience more air resistance than the skydiver falling with a parachute. The parachute increases the surface area of the skydiver, which increases air resistance and slows down the fall.
2. If there is no air resistance, all three balls (tennis ball, golf ball, and bowling ball) will hit the ground at the same time. This is because in the absence of air resistance, all objects will fall at the same rate of acceleration due to gravity.
