2. Motion
Motion occurs when there is a change in position of an object with respect to a reference starting point.

3. Position The location of the object.
We know an object has changed position based on its reference starting point (RSP)

4. Direction
The line or path along which something is moving pointing or aiming.
We describe direction using:

5. Displacement (Final Position)
The change in position of an object, determined by:
Distance (Meters) from the RSP
Direction (N, S, E, W) from the RSP

6. Distance-Time Graphs Remember:
The steeper the slope the faster the speed.
The flatter the slope the slower the speed.
A straight line represents zero slope.
Constant Speed: When time and distance increase at the same rate. Represented with a straight diagonal line.

7. SPEED Speed=Distance/Time We can find: Speed: V=d/t Time: t=d/v
Distance: d=v·t

8. Velocity Velocity can be positive or negative.
Velocity MUST have a direction.
You use the EXACT SAME FORMULA to find velocity that you do speed.
