Answer: acceleration.
- A acceleration
- B landing velocity
- C time of fall
- D momentum
Correct answer: A. acceleration
Explanation: In free fall every body has the same acceleration g, regardless of mass or height.
On a velocity-time graph for uniform acceleration, the slope of the line gives the acceleration and the shaded area under the line gives the displacement.
