Worksheet on air resistance featuring questions, a diagram, and space for student responses.

I can see this is a worksheet about air resistance with several questions. Let me work through each question step by step.

Question 1: Which object has more air resistance? Explain your answer.
- The image shows a parachute and a box
- Air resistance depends on surface area - objects with larger surface areas experience more air resistance
- A parachute has a much larger surface area than a box of similar mass
- Answer: The parachute has more air resistance because it has a larger surface area.

Question 2: Which object will fall the fastest?
- Objects with less air resistance fall faster
- The box has less air resistance (smaller surface area)
- Answer: The box will fall faster.

Question 3: If you drop these two objects from the same height, how will their speeds compare at the end of the experiment?
- The box experiences less air resistance, so it accelerates more
- The parachute experiences more air resistance, which slows it down
- At the end, the box will be moving faster
- Answer: The box will be moving faster than the parachute at the end.

Question 4: How could you make both objects fall at the same speed?
- To make them fall at the same speed, we need to balance the forces
- We could add weight to the parachute OR reduce its surface area
- Or we could attach something to increase the box's air resistance
- Answer: Add weight to the parachute or reduce its size, or increase the box's surface area (like adding wings).

Question 5: What conditions would have to exist for these two objects to hit the ground at the same time?
- In a vacuum (no air), all objects fall at the same rate regardless of shape or mass
- This is because there would be no air resistance
- Answer: They would need to be in a vacuum where there is no air resistance.

Question 6: What will happen to each object's acceleration as it falls?
- Initially, both objects accelerate due to gravity
- As they fall faster, air resistance increases
- Eventually, they reach terminal velocity when air resistance equals gravity
- At terminal velocity, acceleration becomes zero
- Answer: Both objects will initially accelerate, but as they fall faster, air resistance increases until they reach terminal velocity where acceleration becomes zero. The box will reach a higher terminal velocity than the parachute.

Final Answer:
1. Parachute - it has more surface area
2. Box - less air resistance
3. Box will be moving faster
4. Add weight to parachute or increase box's surface area
5. In a vacuum (no air)
6. Both accelerate initially, then reach terminal velocity where acceleration becomes zero; box reaches higher terminal velocity
