1. PHYSICS 2.4 Acceleration 1. Do they start at the same point? 2. Who is traveling faster? 3. What happens at t=5s? 4.Describe the velocity of both. 5.What do you think their acceleration is? Consider the position graph for runners A and B

2. Vocabulary Position - Location of an object at a certain time. Velocity – Change in Location over time. Acceleration - Change in Velocity over time. PHYSICS 2.2 Acceleration

3. 1. Calculate the acceleration in km/h/s and in m/s/s. Graphs are in meters and seconds. 1. Construct an acceleration vs. time graph. 2. Construct a velocity vs. time graph. 3. Construct a position vs. time graph. PHYSICS 2.4 Acceleration Calculations A cheetah can reach a speed of 99 km/h in 3 seconds at a constant acceleration.
