Speed and direction Yes, changing at the same time.
From the vocabulary, we know it is steady change in velocity Essentially, a constant rate change in velocity Or…velocity is changing the same amount each second www.youtube.com /watch?v=BGfPU_g yqm8 www.youtube.com /watch?v=BGfPU_g yqm8
a = v f – v i t a – acceleration v f – final velocity v i – initial velocity t – time Units? Try some problems.
1. A car traveling at 10 m/s starts to decelerate steadily. It comes to a complete stop in 20 seconds. 2. An airplane travels down the runway for 4.0 seconds with an acceleration of 9.0 m/s 2.
Demonstrated on a speed vs. time graph The slope demonstrates acceleration Or…increasing or decreasing slope of distance-time graph
Explain how acceleration is considered a rate? It is a vector too… what does that mean? What kind of graph shows acceleration?
