1. Insanely Super Important Kinematics Terms

2. Kinematics The study of the motion of objects- does not deal with the forces that caused the motion

3. Scalars  A measurement that only gives a numerical value. NO DIRECTION!!  Magnitude is the fancy physics word meaning ONLY numerical value  ex: Time, temperature, mass

4. VECTORS  A numerical quantity AND direction  Ex: velocity, acceleration  Ex: 22 m/s North

5. The location of an object

6. Displacement  The change in position of an object in motion.  Distance from its origin  A vector

7. Distance Total length traveled A scalar measurement

8. Speed (s)  Distance traveled over a period of time  Does not give direction

9. Speed cont….  Instantaneous: Speed at a given moment. (radar gun) Instantaneous: Speed at a given moment. (radar gun)  Average: total distance over total time traveled  Constant: speed does not increase or decrease (cruise control)

10. Velocity (v)  Change of displacement over time in a given direction Change of displacement over time in a given direction *Add in direction

11. Velocity Cont…  Average : total distance over total time traveled in a given direction  Ex: 30 mph due East  Instantaneous: Velocity at a given moment in time  Constant: No increase or decrease in velocity in a set direction

12. Initial Velocity (V i )  Starting Velocity

13. Final Velocity (V f )  Velocity at a 2 nd point or an end point

14. Acceleration (a)  Change in velocity in a given amount of time  Units are m/s 2

15. Acceleration Cont…  Average: the change in velocity divided by an elapsed time.  Instantaneous: acceleration at a given instant.  Constant: Velocity is changing the same amount each second  Ex: Acceleration due to gravity = 9.8m/s/s
