Mini-Quiz: Gravity Equations for Falling Objects

1. If you know how long an object has been falling, what information can you calculate?

   The velocity and displacement traveled for that time periodCorrect. You know about gravity equations. Which version of g to useSorry, not correct. Try another button. The time it has been fallingGood try, but not right. Select another answer.

2. How far has a falling object traveled when it reaches a velocity of 8 ft/s?

   32 ftSorry, not correct. Try another button. 8 ftOops! Wrong answer. Re-read the question and try again. 1 ftThat is Correct. You have great potential.

3. What is the equation for the time it takes to fall a given displacement?

   v = √(2gy)Good try, but not right. Select another answer. t = √(2y/g)Correct. You know about gravity equations. t = v/gOops! Wrong answer. Re-read the question and try again.
