What happens to the velocity of the ball in the X direction as it falls?

1

What happens to the velocity of the ball in the Y direction as it falls?

1

What is the initial velocity in the Y direction?

1

What is the final velocity in the Y direction? On level students - Use the spreadsheet.

1

Which is true about the vertical velocity and horizontal velocity?

1

How long does it take the ball to reach the ground? On level students - use the spreadsheet.

1

When there is no air resistance, why does the vertical componant of a projectile's velocity change with time where the horizontal componant doesn't?

1

A ball is launched straight up. When is the velocity of the ball 0?

1

a projectile is launched vertically at 100 m/s. If you neglect air resistance, when will the projectile return to the same velocity? What about the same speed?

1

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

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

1

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

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

1

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?

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?
