Introduction:
Although all motion is relative, once a point of reference is chosen we have the tools to describe
the motion of any object very accurately. In such a case the motion of an object must fit into
one of the following categories: constant velocity, constant acceleration, or changing acceleration.
For our purposes, we will limit our study of moving objects to constant velocity and constant
acceleration. |

For your test you should be able to:
|
|
1) Define the following vocabulary words:
|
| Velocity (v) |
Acceleration (a) |
Projectile |
Uniform Motion |
| Uniform Acceleration |
Position (x or y) |
"g" |
1 dimension |
| 2 dimensions |
Kinematics |
Initial Position (xo) |
Initial Velocity (vo) |
| Reference Frame |
Range |
Free Fall |
Launch Angle |
| Instantaneous Velocity |
Instantaneous Accleration |
Average Velocity |
Average Acceleration |
|
2) Describe the difference between velocity and acceleration.
|
|
3) Make graphs of position, velocity, and acceleration given one of the others.
|
|
4) Calculate position, velocity, acceleration, or time in various situations.
|
|
5) Understand that sign conventions in physics indicate direction rather than value.
|
|
6) Analyze the motion of a projectile.
|
|
7) Describe motion in two dimensions and the independence of all factors excepting time.
|
|
8) Explain physical situations using instantaneous conditions.
|
|
9) Explain why gravitational acceleration is independent of mass in a vacuum.
