Question 1.
What is the value of acceleration due to gravity?
Show hintHide hint
Remember, it’s a constant value affecting all falling objects.
Question 2.
What does free fall mean?
Show hintHide hint
Think about what happens when nothing else affects the object.
3Question 3.
What is the acceleration due to gravity on Earth?
- 9.8 m/s²
- 9.8 km/h²
- 9.8 m/h²
Show hintHide hint
It affects all objects in free fall.
4Question 4.
True or False: An object in free fall has zero velocity.
- True
- False
Show hintHide hint
Consider the motion of a dropped object over time.
Question 5.
An object is thrown straight up with an initial velocity of 35 m/s. Calculate how high it will go before it starts falling back down.
Show hintHide hint
Remember that at the peak, the final velocity v will be 0.
Question 6.
A feather and a stone are dropped in a vacuum. Explain what happens and compare it to a feather and stone dropped in the air.
Show hintHide hint
