What is the definition and formula for impulse?

In this tutorial you will learn about impulse.

Summary

  1. F with an arrow- the force vector
  2. J- the symbol for impulse
  3. ∆t- the change in time
  4. J with an arrow- the impulse vector
  5. N- Newtons
  6. s- seconds
  7. kg- kilograms
  8. m/s- meters per second

Notes

    1. When you see capital J, you should think Impulse!
    1. Impulse and force point in the same direction, but they are not the same thing!
    1. When you plug in F=0 into the Impulse equation, you get zero Impulse
    1. Don't confuse Impulse and Force!
