# 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

Horizontal and vertical components are independent

Equations of motion for projectiles

Characteristics of projectiles

Demonstration on what happens as initial conditions are altered

• 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
