Projectile motion

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!

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!!!
