Projectile Motion

3
Once a difficult problem for cannoneers If the vertical and horizontal components are separated, the problem becomes simple.

4
Projectile Motion Horizontal – simple as a ball rolling across the table Use equations like d = v x t

5
Projectile Motion Vertical – simple as a free falling gravity problem Use equations like d= 1/2 gt 2 and A = V/T

6
Projectile Motion NOTE: Air and other resistance is being ignored for the time being.

7
Projectile Motion 8 km/s 29,000 km/hr 18,000 MPH

Projectile Motion

16
Trajectory Up to a 45 degree angle – greater distance at greater angle After 45 degree – greater height, less distance 45 degree gives the greatest distance Any two angles that add to 90 degrees will hit the same place
