- video - Ballistics Cart
(
During the group quiz I will have a problem "ballistic cart on an incline". So I will need a small inclined version.)

(
For Friday I will use the cart with the weight)
- video - The Atwood Machine
- photos - Tension in a String
(The version I am request is much simpler: I need one pulley, one string, a scale, and a weight. Here is what I plan to do:
- beginning of class: put weight on one side and scale on the other (held by hand), point out the force is equal to mg
- end of class (together with window washer problem): hook the other side of the scale to the same weight (so both string ends attached to the weight but with the scale measuring one string tension). Point out the tension is now half of weight.
(If too complicated, ignore)
)
