Question 1
1.

If all these left the table at the last moment, which would be the last to hit the ground?

Question 2
2.

Consider the following formula
Where F is the force of gravity between two objects
m1 is the mass of one object
m2 is the mass of another object
r is the distance between the two objects
G is a constant.

When the distance between two objects increases, the force of gravity between those objects

Question 3
3.

Consider the following formula
Where F is the force of drag from air resistance
ρ is how thick and viscous the air is
v is the velocity of the object
C_D, the drag coefficient is a number that is specific to the shape and material an object is made of. The
A is the surface area of object falling. Note - the viscosity of the air, the drag coefficient and the surface area of the object do not change. consider what variables of the equation DO change.

As a skydiver falls, her speed increases due to the acceleration due to gravity. What effect does increasing speed have on the force of air resistance

Question 4
4.

When you jump upward, your hang-time is the time your feet are off the ground. Does hang-time depend on

Question 5
5.

How many meters had the ball travelled after 4 seconds?

Question 6
6.

Compare the time periods 0-2 seconds and 2-4 seconds.
Which statement is true?

Question 7
7.

Look at the slope, or steepness of the curve on the graph.
What happens to the curve as time passes?

Question 8
8.

Which statement best describes the ball's speed as it travells down the ramp?

Question 9
9.
