A pair of tennis balls fall through the air from a tall building. One ball is regular and the other is filled with lead pellets. Air resistance just before they hit is actually greater for the:
Understand the Problem
The question is asking about the difference in air resistance experienced by two tennis balls of different types (regular and lead-filled) just before they hit the ground. It is focused on understanding how the mass and structure of the balls affect their interaction with air as they fall.
Answer
Lead-filled ball.
The final answer is the lead-filled ball.
Answer for screen readers
The final answer is the lead-filled ball.
More Information
The lead-filled ball experiences greater air resistance just before hitting because its higher mass allows it to fall faster than the regular ball.
Tips
A common mistake is assuming that if two objects are of equal size, they will have the same air resistance. Remember that speed also plays a role.
