Sports Unit: Projectiles and Circular Motion

Rating:
Rating
(0)
Description:

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?

Horizontally Launched Projectiles (Part 1)

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