 How do you find the x and the y component of velocity?  Is there such a thing as centrifugal force (pulling to the outside)?  How often does centripetal force play a role in our lives?

Mr. Schlamb

 An object shot through the air is called a projectile.  The only force acting on a projectile if we neglect air resistance is gravity  All projectiles follow a parabolic path this path is its trajectory

 If you know the initial thrust put on a projectile you can calculate its trajectory.  So you can find distance, max height and horizontal and vertical velocity

 If you were on the golf course and someone hit a ball you would see it go up and back down  If you looked at it from a jet is would look like it went straight along the ground  Both vertical and horizontal motion are dependent of each other, they are the same but separate.

 If I had two balls, one was dropped over the edge of the table and the other was given a horizontal velocity off the table which one will hit the ground first? Assume they were both falling off the table at the same time.

 They will land at the same time.  Since horizontal motion and vertical motion are independent of each other the extra horizontal motion does not affect the rate at which the ball falls. Gravity still pulls at a rate of 9.8m/s squared.

 Break the problem into two separate problems  One x direction problem and one y direction problem  You may use vectors to help you visualize the problem

 Max height see board all others have already been given but will be on board as well

 Grab a piece of paper and a book everyone needs a book and a piece of paper see board for directions
