Learning Targets

Students should understand the motion of projectiles in a uniform gravitational field, so they can:

(7) Write down expressions for the horizontal and vertical components of velocity and position as functions of time, and sketch or identify graphs of these components.

(8) Use these expressions in analyzing the motion of a projectile that is projected with an arbitrary initial velocity.

(9) Students should be able to analyze situations in which a particle remains at rest, or moves with constant velocity, under the influence of several forces.

(12) Draw a well-labeled, free-body diagram showing all real forces that act on the object.
