How can we break objects propelled horizontally into components to predict motion? Horizontally Launched Projectile Think Pair Share If you are a pilot flying with a constant velocity trying to drop a package to the island below. Where should you release the package? Justify your answer. Observe-Infer-Wonder Someone threw a tennis ball horizontally off a cliff. Another person on the same cliff dropped a tennis ball at the same time as the first ball was thrown off the cliff. Which ball will hit the bottom of the cliff first? Why? Demo Let’s test this out with a demo Answer Someone threw a tennis ball horizontally off a cliff. Another person on the same cliff dropped a tennis ball at the same time as the first ball was thrown off the cliff. Which ball will hit the bottom of the cliff first? Why? THEY WILL HIT THE GROUND AT THE SAME TIME!!!!! Big Takeaway There are two motions, a HORIZONTAL MOTION and a VERTICAL MOTION. They are INDEPENDENT of each other. Vertical and Horizontal. They WILL HIT THE GROUND AT THE SAME TIME REGARDLESS as long as the other object is thrown horizontally. Now take out your notes and turn to page 4 2-Dimensional Motion  also fall vertically at a constant rate of -9.81 m/s2 have 2 Velocities and Accelerations ○ Horizontal Velocity and Acceleration ○ Vertical Velocity and Acceleration Objects Propelled They are independent of Horizontally each other!  Horizontal Velocity = Vx Horizontal Acceleration = ax Vertical Velocity = Vy Vertical Acceleration = ay Initial Horizontal Velocity = Vix Objects Propelled Initial Vertical Velocity = Viy Horizontally  Vix = determined by the launch Vx is constant! (neglect air resistance) ax is 0 m/s2 Objects Propelled Horizontally  Viy = 0 m/s (Initial Vertical Velocity) Vy changes by…. g = -9.8 or -10 m/s2 The object is still in free fall!
