Document Summary

Theme 1 module 2: vectors and sig figs: scalar: includes magnitude but no directional info. (ex. !2: angle in degress * pi/180 =rads , rads 8 180/ pi = angle in degrees, signi cant numbers slow us to express numbers at equal accuracy, non-zero digits are typically assumed to be signi cant. (ex. 23. 5: zeroes on the interior of a number are signi cant. (ex. 2009: zeros on the right side of the number are typically signi cant. (ex. 44. 5: place holder zeros aren"t signi cant. (ex. 0. 04560, arithmetic with sig figs. Motion diagrams show time intervals between changes in position (ex. Slowing down x x x x xxx: position: where the object is (x, displacement: how much the position has changed (delta x), a vector quantity, velocity: how quickly displacement occurs (delta x/time, v), a vector quantity. Theme 2 module 2 mechanics and forces: force: any interaction between two objects. Can be a contact or non contact.
