Elephant and Feather Worksheet

Each of these statements is false.  Explain why each is false. 

1. The elephant encounters a smaller force of air resistance than the feather and therefore falls faster.

2. The elephant has a greater acceleration of gravity than the feather and therefore falls faster.

3. Both elephant and feather have the same force of gravity, yet the acceleration of gravity is greatest for the elephant.

4. Both elephant and feather have the same force of gravity, yet the feather experiences a greater air resistance.

5. Each object experiences the same amount of air resistance, yet the elephant experiences the greatest force of gravity.

6. Each object experiences the same amount of air resistance, yet the feather experiences the greatest force of gravity.

7. The feather weighs more than the elephant, and therefore will not accelerate as rapidly as the elephant.

8. Both elephant and feather weigh the same amount, yet the greater mass of the feather leads to a smaller acceleration.

9. The elephant experiences less air resistance and than the feather and thus reaches a larger terminal velocity.

10. The feather experiences more air resistance than the elephant and thus reaches a smaller terminal velocity.

11. The elephant and the feather encounter the same amount of air resistance, yet the elephant has a greater terminal velocity.
