As the roller coaster cars go down the first hill, they go (1.) (faster and faster/slower and slower). This change in speed means their (2.) (velocity/reference point) also changes. When the cars climb the next hill, they (3.) (speed up/slow down). This causes their (4.) (velocity/reference point) to change again. When the cars hit a curve, their (5.) (velocity/reference point) changes again! (6.) (Acceleration/Speed) is a measure of the change in (7.) (velocity/motion) during a period of time.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
