Bell Ringer: What are Newton's 1st and 2nd laws?
Finish projectile labs (due tomorrow)
Notes - Newton's 3rd law
For every action (force), there is an equal and opposite reaction (force)
e.g. When you push on a wall, the wall pushes back on you with the same force
e.g. When you kick a soccer ball, your foot applies a force to the ball which causes it to move, and the ball applies the same force back on your foot which causes your foot to slow down.
e.g. When a rocket is lifting off, the rocket applies a downward force on the fuel it is burning, and the fuel applies an upward force on the rocket (causing it to lift off)
Building bottle rockets (will launch these next time we have good weather for it)
