Projectile Motion

2D Motion2011-2012Projectile MotionWhat is Projectile Motion?Projectile motion is the motion of an object that is being thrown or launched.

The object may be launched horizontally or at an angle.What is Projectile Motion?Projectile any object that is thrown/shot through the air

Trajectory the projectiles path

A projectile will always follow a parabolic trajectory.Example of HorizontalLets watch a clip from Looney Tunes.

Is this realistic? Why or why not?

What Actually Happens?

But its not!

Think back to last chapter where we separated the vertical and horizontal components.So Now for the EquationsHorizontal:vx=dx/tVertical:dy = vyit + 1/2 gt2vyf2 = vyi2 + 2gdyvyf = vyi + gt

Solving ProblemsIsolate the horizontal and vertical components into a table and solve for each piece.x yExamplePage 150, Problem 1HomeworkPage 150, Problems 2, 3
