Science Starter! There is an interesting monkey at the zoo. The zookeeper feeds the monkey by shooting bananas from a banana cannon to the monkey in the tree. This particular monkey has a habit of dropping from the tree the moment that the banana leaves the muzzle of the cannon. If the monkey lets go of the tree the moment that the banana is fired, will it catch the banana? Describe what you believe will happen and why.
Two Dimensional Motion KEY IDEA: Horizontal motion and Vertical motion are INDEPENDENT of each other. “Cliff” problems: Vertical Motion: ay = - 9.8 m/s2 (Free – Fall) Horizontal Motion: ax = 0 m/s2
Kinematics Equations Vertical Horizontal
Representing Quantities Vectors: Remember: Any quantity with magnitude and direction (Displacement, Velocity, Acceleration) Represented by an ARROW, that is proportional in size and direction. V = 5 m/s East V = 2 m/s North
Actual Velocity At t = 2s: Vx = + 20 m/s Vy = - 19.6 m/s
Resultant Vectors Vx Pythagorean Theorem: = + Vy V
Problem Solving • Draw a picture and include labels! • List variables in “x” and “y” directions SEPERATELY!
