Students will understand two-dimensional motion, such as: projectiles, and objects moving in a circular path.

Knowledge/Understanding:

1) I can find the x-and y-vector components of two-dimensional motion.

2) I can find the height and range of projectiles

3) I can understand the motion of a turning vehicle.

4) I can understand how centripetal forces keep an object toward the center of the circle.

Students will be able to use the information in this section to complete their project of a video of a sporting event where they are the sports commentators discussing the physics involved.

Essential Questions:

1) What factors describe the motion of a vehicle making a turn?

2) How does the acceleration due to gravity affect the projectiles?

3) What determines the range and height of a projectile?

Tutorial

These notes will correlate with all the different screencasts made for this unit on projectiles and circular motion.

Students will compare projectile motion to free fall, to solve equations. We will use basic trig of right triangles to solve our vector analysis.
