Students will describe motion in terms of displacement, velocity, acceleration and time. 1. Define, qualitatively and quantitatively, displacement, velocity and acceleration. 2. Define, operationally, and compare and contrast scalar and vector quantities. 3. Explain, qualitatively and quantitatively, uniform and uniformly accelerated motion when provided with written descriptions and numerical and graphical data 4. Interpret, quantitatively, the motion of one object relative to another, using displacement and velocity vectors 5. Explain, quantitatively, two-dimensional motion in a horizontal or vertical plane, using vector components.

A) If a projectile was like a year of school, how would you describe the path of the school year.



B) " Suppose a zookeeper must shoot a banana from a banana cannon to a monkey who hangs from the limb of a tree. This particular monkey has a habit of dropping from the tree the moment that the banana leaves the muzzle of the cannon. The zookeeper is faced with the dilemma of where to aim the banana cannon in order to hit the monkey. If the monkey lets go of the tree the moment that the banana is //fired//, then where should she aim the banana cannon? To ponder this question, first consider a scenario in which there is no gravity acting on either the banana or the monkey. What would be the path of the banana? Would the banana hit the monkey?"

C) Two spheres are shot at the same point on the moon. Sphere A is shot from a canon at 45degrees and is given a vertical velocity of 10m/s, and horizontal velocity of 8m/s. Sphere B is shot at the same time as Sphere A and is given a horizontal velocity of 10m/s. Describe the paths of Sphere A compared to sphere B using a graph. Create a page called SPHERES: Your Name.

D) Professor Khan has a few choice videos. Log in to view his videos, and feel free to harness Khan's brain power to help you create your own projectile questions. Complete and post one "one dimensional" projectile question, and one "two dimensional" projectile question.
