Title: Going Ballisitics: Sorting Out Vectors
Course: Physics copy 1

Cody is riding the roller coaster on a level straightaway at Canada's Wonderland when he accidentally drops his accelerometer out of the car. The accelerometer dutiful records it motion before it hits the ground.

Cody is able to download the motion broken into its components, but he doesn't know which is which. He does kno the following:
1. One set of vectors describes acceleration
2. One set describes velocity
3. One set describes displacement.

He has sketched each set of vectors for three equally spaced times after their fall from the roller coaster t_1, t_2 and t_3.

Which set is which?

This is a communication mark.

Do you understand how vector diagrams related to the motion of an object? Can you relate changes in vector diagrams to kinematics? Do you understand components and can you apply the concept to projectile motion? | You have difficulty relating the vector representation to the motion of the object. | You have identified characteristics of the component vectors and have related them to the motion of the object. There are some inconsistencies in your reasoning. | You have identified the characteristics of the components and you have related them to the motion of the object. Your reasoning is clear and concise. | You have identified the characteristics of the component vectors and you have clearly and concisely related them to the motion of the dropped accelerometer. You have related the component vectors to kinematics. Your reasoning is consistent and clear. There is evidence of growth in your understanding in your subsequent posts.
