    Projectile Motion mini LAB
Purpose –
     Projectile Motion mini LAB
Purpose – to carefully observe the motion of a
   projectile and analyze the changes that
   occur during that motion. From this, the
   laws that govern projectile motion can be
   developed.

   laws that govern projectile motion can be
   developed.

Procedure – record the position of a projectile
   along the X and Y axis’ at each time
   interval.
                   DATA
      Time       X (m)    Vx     Y (m) Vy (m/s)
Vid frms   (s)           (m/s)
   0        0
                  Analysis
1. Plot the position of the object on a graph.
   - Draw just like we did on the screen.
   - Label axis’ Position (m)
   - Number every other line by 0.1 m.

3. Draw the Vx velocity vectors at each position.

4. Draw the Vy velocity vectors at each position.
               Conclusion
1. What happens to Vy from 0 sec to 0.5 sec ?

2. What happens to Vx from 0 sec to 0.5 sec ?

3. How would you describe the motion of a
   horizontally thrown projectile?
    a. Vertically
    b. Horizontally
Projectile Motion
     Projectile Motion

Vx
        Projectile Motion

Vx is constant unless there is air resistance
        Projectile Motion

Vx is constant unless there is air resistance




Vy
        Projectile Motion

Vx is constant unless there is air resistance




Vy is constantly changing because the
  object is undergoing negative acceleration
                               (-a)
            EQUATIONS

 ∆x = vx • t        vx =    ∆x
                              t

Horizontal Launch          Up and Down

  ∆ y = ½ g • t2           ∆y = ½ g • ( t/2 )2

  vy = g • t               vy = g • ( t/2 )
