Q6. Given your current understanding of free fall, what do you think the difference will be

between the free fall of a coin and the free fall of an extended object such as crumbled up

piece of newspaper? (This is your hypothesis for Procedure I.)

Q7. Given your current understanding of free fall, what do you think the difference will

be between the free fall of a coin from different heights? (This is your hypothesis for

Procedure II.)/nQ7. Use the number line above to calculate the distances and displacements for the

paths listed. Don't forget to include the units.

From A to B to M to N

From C to A to G to D

From J to I to E to H

From F to B to K to F

Distance

Displacement/nQ8. For each of the paths from Q1, calculate the average speed and the average

velocity if the path is traveled in 5.0 seconds. Don't forget to include the units. Use

this Formula Reference Sheet (click this highlighted link for information) to

remember the formulas you need. Show work with answers.

Average velocity

From A to B to M to N

From C to A to G to D

From J to I to E to H

From F to B to K to F

Average speed/nsign of the acceleration! Whether you are speeding up or slowing down, you are merely accelerating

Let's sure that the forward direction is positive and the band direction is neve

Acar starting from rest to get out of a parking spot, backs up moves in the negative direction, and it speeds up with a negative acceleration. Then the car comes to stop after

backing up with a positive acceleration

Acar starting from rest to continue his drive after getting out of the parking spot moves forward it spends

negative acceleration

The correct way of finding out whether an object speeds ap or slow down is to say

If the acceleration and the velocity point in the same direction, then the object sp

If the acceleration points in the opposite direction of the velocity, then the object f

Q9. You throw a ball into the air, it reaches a certain height and then comes back to you.

(a) On the way up, what are the directions of the velocity and the acceleration? Does the ball

speed up or slow down?

(b) On the way down, what are the directions of the velocity and the acceleration? Does the

ball speed up or slow down?

Q10. (a) Is a car going around a curve at 50 km/hr experiencing acceleration? Explain why

or why not.

(b) Is a skateboard coasting down a hill at 2 m/s experiencing acceleration? Explain why or

why not.

(c) Is a car stopping at an intersection experiencing acceleration? Explain why or why not.
