Chapter 3: 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: Example 1, Example 2, Example 3, Example 4

Let's begin simply with purely vertical motion

Now let's add horizontal motion

Horizontal and vertical components are independent

  • What happens to horizontal displacement as velocity is increased?
  • What happens to the optimal initial angle for distance when release height is increased?

  • Demonstration on what happens as initial conditions are altered

    Things get more complex when takeoff and landing heights are different
