What is the formula used to calculate the acceleration due to gravity (g) using the freefall method?.
- A.g = 2h / t^2
- B.g = v / t
- C.g = F / m
- D.g = m / V
Model answer
What a good answer should say
- g = 2h / t^2
Explanation
Why this works
The formula g = 2h / t^2 is derived from the equations of motion for an object in freefall, where h is the height fallen and t is the time taken. This formula allows us to calculate the acceleration due to gravity based on the distance fallen and the time taken.
