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

a ball dropped from rest off a table

a ball rolled off a table at a velocity of 1 m/s east

a ball rolled off a table at a velocity of 10 m/s east

A ball launched off a table at a velocity of 10 m/s east and 45° up.

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

increases proportionally (linearly)

increases significantly faster (non-linearly)

decreases proportionally (linearly)

decreases significantly faster (non-linearly)

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

The force of drag increases, total force downwards increases

the force of drag decreases, total force downwards decreases

the force of drag increases, total force downwards decreases

the force of drag decreases, total force downwards increases

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

The vertical component of your initial velocity

The horizontal component of your initial velocity

both vertical and horizontal components

How many meters had the ball travelled after 4 seconds?

1

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

The ball travelled farther between 0 and 2 seconds

The ball travelled farther between 2 and 4 seconds

The ball travelled the same distance in both time periods

No way to tell from the graph

1

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

1

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

It is going the same speed the whole time

It is speeding up

It is slowing down

There is no way to tell
