1. Notes 1: Measuring Motion

2. Position
This is precisely where an object is located
You are here

3. Distance the total length of the path an object has moved 1 Foot
=6 Feet
2 Foot
1 Foot

4. Displacement
the shortest distance from the initial position and the final position
1 Foot
1 Foot
1 Foot
=1 Foot
2 Foot
1 Foot

5. Gravity
the attractive force that exists between any two objects that have mass
Acceleration due to Gravity on earth is -9.8 m/s2
-9.8 meters per second

6. Average Speed
the average of all instantaneous speeds; calculated by “distance divided by time”
4mph
3mph
5mph
3mph
5 mph
= 4 mph

7. Instantaneous Speed the speed at any given instant in time 4mph 3mph
Instantaneous Speed here?
= 5 mph

8. Relative Speed The speed of an object compared to a second object
Which One is Faster?

9. Velocity how fast an object is moving and what direction
20mph Traveling East

10. Acceleration the rate of change of velocity
(Remember: Velocity is speed with direction)
0 – 60mph in 6 seconds

11. Scalar Measurement of magnitude (size) only
Examples: Distance, speed, temperature

12. Vector Measurement of Magnitude (size) and a direction
Examples: Velocity, Change in temperature
