  1. What is Projectile Motion?

  2. Instructional Objectives: • Students will be able to: • Define Projectile Motion • Distinguish between the different types of projectile motion • Apply the concept to a toy car and measure its velocity

  3. Projectile Motion • Two-dimensional motion of an object • Vertical • Horizontal

  4. Types of Projectile Motion • Horizontal • Motion of a ball rolling freely along a level surface • Horizontal velocity is ALWAYS constant • Vertical • Motion of a freely falling object • Force due to gravity • Vertical component of velocity changes with time • Parabolic • Path traced by an object accelerating only in the vertical direction while moving at constant horizontal velocity

  5. Examples of Projectile Motion • Launching a Cannon ball

  6. Equations • X- Component • Y- Component • Vectors Note: g= 9.8 m/s^2

  7. Factors Affecting Projectile Motion • What two factors would affect projectile motion? • Angle • Initial velocity Initial Velocity Angle

  8. Class Exercise An object is fired from the ground at 100 meters per second at an angle of 30 degrees with the horizontal • Calculate the horizontal and vertical components of the initial velocity • After 2.0 seconds, how far has the object traveled in the horizontal direction? • How high is the object at this point?

  9. Solution • Part a • Part b • Part c

  10. Applications Any Ideas?
