Document Summary

Projectile aka free-fall following a curved path, the only force on the object is gravity. Consider moving object as if a single point without size or shape, no distinction btwn top + bottom or front + back. Treat as if all mass were concentrated into a single point this object is a particle. Vector v = lim t0 ( r/ t) = dr/dt [m/s] Vector vavg = r1 - r0 = r [m/s] basically overlaying all frames of a movie strip on. Vector a = lim t0 ( v/ t) = dv/dt [m/s2] top of each other. of an object at several instants in time. more space btwn dots = moving faster. vectors = made up 2#s (magnitude + direction/angle), always straight ex. Methods: tip-to-tail, parallelogram, components (using x-y axis, can add on calculator) Tip-to-tail: draw a, place b tail @ a tip, draw arrow from a tail to b tip.
