2. Distance How much ground an object has covered

3. Velocity How fast an object is going in a certain direction.

4. Acceleration How quickly an object slows down or speeds up.

5. Force A push or pull that causes an object to move, stop, or change direction. The larger the weight, the larger the force. The larger the force, the larger the acceleration.

7. Jet Fighter vs Car vs Motorcycle Plane passes bike at about 20 seconds [A] Car passes bike at about 25 seconds [B] Plane needs about 2000 ft to take off MOTORCYCLE: top speed 175 MPH (280 km/hr or 80 m/sec). CAR: top speed 200 MPH (325 km/hr or 90 m/sec). JET FIGHTER: top speed 1,400 MPH (about MACH 2) take off speed 200 MPH.

8. Jet Fighter versus Car versus Motorcycle MOTORCYCLE: Accelerates fastest off the starting line (because it is the lightest). But its top speed is only about 175 MPH (280 km/hr or 80 m/sec). CAR:Accelerates second fastest off the starting line (because it is the next lightest). But top speed is only about 200 MPH (325 km/hr or 90 m/sec). JET FIGHTER: Slowest of the starting line (it is by far the heaviest). But is accelerates for the longest time - 0.6 g for more than 25 seconds. But top speed MACH 2 or 1,400 MPH with a take off speed of about 200-250 MPH.

9. Sprinter 100 m Split Times World Record & Grade 5s Sprinters accelerate fairly quickly (2 to 4 seconds) and then try and keep at that speed (velocity). World Record: 100 meters in about 9.7 s Top speed about 12 meters/second or 27 MPH Grade 5 Fastest 100 m in about 13.8 s Top speed about 8 meters/second or 18 MPH Grade 5 Fastest 100 m in about 17 s Top speed about 7 meters/second or 15 MPH but fades at end.

10. Sprinter 40 m Split Times World Record & Grade 5s Sprinters accelerate fairly quickly (2 to 4 seconds) and then try and keep at that speed (velocity). World Record: 40 meters in about 4.5 s Top speed about 12 meters/second or 27 MPH Grade 5 Fastest 40 m in about 6.5 s Top speed about 8 meters/second or 18 MPH Grade 5 Fastest 40 m in about 7.2 s Top speed about 7 meters/second or 15 MPH and no fade! 1

12. Friction A force that happens when things rub against each other.

13. Gravity The force of attraction between all masses in the universe

14. Frequency The number of times something happens within a given time period.
