Thought experiment: we claim that the air track is frictionless, but this is not entirely true. how would our newton's 2nd law models (eq. 1 and eq. 3) of the two systems studied in this lab change if we were to account for the force of friction acting on the glider as it travels across the track? draw force diagrams to you. use f to denote the mathematical term for the force of friction. ww hence a fixed force (f = mhg). mass will be added to the glider, so that: f=mng = (m + mn)a (eq. 1) resulting in: fmg sin 0= ma (eq. 3)

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
