|
|
| 6. | In
graphing motion, the steepness of the slope depends on a. | how quickly or
slowly the object is moving. | c. | when the object
began moving. | b. | how far the object has moved. | d. | the direction the object is moving. | | | | |
|
|
| 7. | On a
graph showing distance versus time, a horizontal line represents an object that is a. | moving at a
constant speed. | c. | decreasing its
speed. | b. | increasing its speed. | d. | not moving at all. | | | | |
|
|
| 8. | To
determine the acceleration rate of an object, you must calculate the change in velocity during each
unit of a. | speed. | b. | time. | c. | motion. | d. | deceleration. | | | | | | | | |
|
|
| 9. | The
formula for determining speed is ... a. | Speed = Distance * Time | c. | Speed = Distance / Time | b. | Speed = Time /

|
| 11. | If
Line B was extended up through the ceiling of the classroom, what would eventually happen to the
line? a. | The line would
continue slanting to the right. | c. | The line would
curve back to the left. | b. | The line would go vertical. | d. | The line would just stop. | | | | |
|
|
| 12. | This
lab illustrates: a. | acceleration due
to gravity in a perfect vacuum. | c. | how acceleration
is shown in cartoons. | b. | the effect of air resistance on
acceleration | d. | all of the
above. | | | | |
|
|
| 13. | The
phrase “terminal velocity” means ... a. | you die when you go very fast. | c. | you reach a point when you can no longer go any
faster. | b. | you stop at a certain point. | d. | you have to turn around and come
back. | | | | |
|
True/False
Indicate whether the sentence or statement is true
or false.
|
|
| 14. | All
of the acceleration calculations on the data chart should have been 9.8 m/sec/sec.
|
|
| 15. | All
average ball drop times were exactly correct. There is no error possible in the
measurements.

not possible to illustrate “terminal velocity” due to air resistance in a two meter
drop.
|
|
| 17. | It IS
possible to achieve 9.8 m/sec/sec acceleration due to gravity on earth IF you drop the object in a
vacuum.
