1. he Ashely is approaching a stoplight moving with a velocity of 30.0 m/s. The light turns yellow, and Ashley applies the breaks and skids to a stop. If her acceleration is -8.00 m/s 2, then determine the distance the car traveled while skidding. WARM UP: to be done in your notebook

3. Acceleration and Motion Graphs

4. VELOCITY TIME graphs This straight line on a v/t graph means that the speed is constant and is not changing over time. A STRAIGHT LINE ON A V/T GRAPH DOES NOT MEAN THE OBJECT IS NOT MOVING. But is does mean there is NO ACCELERATION

5. This graph shows decreasing speed. The moving object is decelerating. SLOWING DOWN

6. Summary of a v/t Graph A B C

7. Compared to a d/t graph Returning to starting position Not moving A B C Constant speed DistanceDistance
