Projectile Motion

Objectives:
  • Use equations of motion for projectiles
  • Determine the optimum release conditions for maximum distance

Projectile Motion

A Projectile is any body that has been set on its path by some force and continues in motion by its own inertia. (Gravity has a major effect on motion).







Examples of Projectiles include: Arrow, Basketball, Shotput, Human Body,Tigers

Let's begin simply with purely vertical motion

Now let's add horizontal motion

Horizontal and vertical components are independent

  • Practice Question:
    Initial Velocity of Projectile
    Vh = 5 m/s
    Vv = 10 m/s
    Flight Time = ?
    Maximum Height = ?
    Horizontal Displacement = ?

    Practice Question:
    Initial Velocity of Projectile

  • V = 20 m/s
    at 45 degrees
    Flight Time = ?
    Maximum Height = ?
    Horizontal Displacement = ?
  • Things get more complex when takeoff and landing heights are different Flight Time
