1. SPEED=DISTANCE TRAVELED OVER TIME TAKEN

   • DISTANCE TRAVELD=SPEED TIMES TIME TAKEN
     • TIME TAKEN=DISTANCE TRAVELED OVER SPEED

2. DISTANCE TIME GRAPH

   • IF DE LINE GO UP DEN DOWN IT GO BACK HOME

3. THE CAR DOWN THE HILL AND GAINS SPEED SO AT THE END OF THE HILL IT GOES FURTHER ALONG THE GROUND

   • AIRODYNAMICS

4. RELATIVE MOTION

   • WHEN SCIENTISTS COMPARE THE MOVEMENT OF TWO OBJECT THEY TALK ABOUT RELATIVE MOTION.
     • IF TWO CARS GET IN A HEAD ON HEAD COLITION AT 60MPH IT WILL BE LIKE CRASHING IN TO A WALL AT 120MPH.
       • IF TWO CARS ARE HEADING THE SAME DIRECTION AND ONE IS GOING 60MPH AND CRASHES INTO ONE GOING 30MPH IT WILL BE LIKE CRASHING INTO A WALL AT 30MPH.

5. A

6. ·

   • PUSH OF THE ENGINE
   • PULLING FORCE OF THE EARTHS GRAVITY
   • LIFT FORCE OF THE WINGS
   • PUSH OF THE AIR RESISTANCE

7. MASS*GRAVITATIONAL FORCE =WEIGHT

   • WEIGHT /MASS =GRAVITATIONAL FORCE
     • WEIGHT/ GRAVITATIONAL FORES =MASS
