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
