Title: Projectile motion


1
Projectile motion
2
Motion in two dimensions
  • Projectile any object that is thrown or
    projected .
  • Object will under go motion in horizontal and
    vertical dimensions

3
  • Trajectoryspecific path that a projectile
    follows. Usually a parabolic curve unless object
    is thrown straight up.

4
Projectile motion
  • We analyze the motion in the horizontal and
    vertical dimension independently of each other!

5

Projectile equations
  • Horizontal dimension
  • Vx d / t dxvt
  • Assume no air resistance
  • Projectiles do not change speed
  • in x dimension

6
Projectile equations
  • Vertical dimension
  • dy vi t 1/2 gt2 vy gt
  • Gravity is prime force vertically

7
Projectile equations
  • Special equations for range and height!!!
