  1. Projectiles About projectile motion To the tune: “The Old Folks at Home” by Stephen Foster C is a comfortable key to sing it in

  2. Projectiles – verse 1 When a thing is thrown and it zips off It will chase a parabolic arc We can do this with a gun or ball Or even Fido’s stick when in the park

  3. Projectiles - Chorus Horizontally, its speed is set Of acceleration that way, it is free Vertically, everything that’s not held up Accelerates to earth, with value “g”

  4. Projectiles – verse 2 An object that’s not held up by anything Will plunge to earth like concrete in free-fall As well as that, in a horizontal sense There is no force that pushes it at all

  5. Projectiles - Chorus Horizontally, its speed is set Of acceleration that way, it is free Vertically, everything that’s not held up Accelerates to earth, with value “g”

  6. Projectiles – verse 3 Projectiles are objects that are in the air Free from almost all external force We ignore all lift and thrust and drag but we Must include the vector, weight, of course

  7. Projectiles - Chorus Horizontally, its speed is set Of acceleration that way, it is free Vertically, everything that’s not held up Accelerates to earth, with value “g”

  8. Projectiles – verse 4 To find the range of anything that’s thrown about We need to find the time until it lands The vertical velocity, when t is nought Combined with “g” will put it in our hands

  9. Projectiles - Chorus Horizontally, its speed is set Of acceleration that way, it is free Vertically, everything that’s not held up Accelerates to earth, with value “g”

  10. Projectiles – verse 5 Finally, now we know our time of flight And the constant horizontal speed We can find the distance ‘til the object drops And thus we then have all the stuff we need

  11. Projectiles - Chorus Horizontally, its speed is set Of acceleration that way, it is free Vertically, everything that’s not held up Accelerates to earth, with value “g”

  12. Projectiles – Chorus – last time Horizontally, its speed is set Of acceleration that way, it is free Vertically, everything that’s not held up Accelerates to earth, with value “g”
