2 Announcement Quiz on Friday (Graphing and Projectile Motion) No HW due Wednesday
3 As the red ball rolls off the edge, a green ball is dropped from rest from the same height at the same time Which one will hit the ground first? They will hit at the SAME TIME!!!
4 Projectile Motion Objective: 1. To view projectile motion as a result of vector independence
5 The same time?!? How?!? The red ball has an initial HORIZONTAL velocity (v ix ) But does not have any initial VERTICAL velocity (v iy = 0) The green ball falls from rest and has no initial velocity IN EITHER DIRECTION! v iy and v ix = 0 v ix
6 One Dimension at a Time Both balls begin with no VERTICAL VELOCITY Both fall the same VERTICAL DISTANCE Both fall with the same ACCELERATION This means that the time of flight IS THE SAME IN BOTH CASES Sideways motion has no influence on time of flight (only height does)
7 MythBusters Video How does this actually look in real life?

11 Day 2 Projectile Motion
12 Horizontally-Launched projectiles In the x-direction, it has constant velocity In the y-direction, it is in free fall (9.8m/s/s) The x and y components have absolutely no affect on each other! (This is called the independence of vectors) The time it takes for an object to fall completely depends on its height, not horizontal velocity.
