Vocabulary: 1.acceleration: rate at which velocity changes over time. 2. Free fall acceleration: an object in free fall is only affected by gravity—causes to accelerate or decelerate.

1. What type of quantity is acceleration? Vector quantity 2. What goes on the y-axis of an acceleration graph? velocity 3. If you acceleration what are you pushing in your car? Gas pedal 4. If you decelerate what are you pushing in your car? brakes

Speed, velocity, and direction 5. What must stay constant in order for acceleration to be “zero”. 6. What are the units for acceleration? Km/h/s or m/s 2 7. What is meant by “positive” acceleration? Direct relationship 8. What type of relationship is seen in a constant acceleration graph? Speeding up

9. When we count sig figs. How do we know how many sig figs our answer should contain? Least amount of sig. figs in your original numbers 10. The slope of a velocity vs. time graph is what rate? ACCELERATION
