Document Summary

Lab 1: show graph for displacement, acceleration, and velocity, identifying average velocity, instantaneous velocity. top line of numbers is distance. second is time it took them to get to that point. The forces we cant see making us move. Forces cause: movement in a linear fashion and movement in a rotational fashion all starts with force: Without a force, cant have an acceleration and therefore no change in the other 3. Centripetal force keeps an object on a circular path. Fluid drag/lift: keep things on on water or in air (e. g. plane in the air) Friction: causes objects to do different things. Reaction forces: applying force to a seat that needs to give back opposite and equal force that i"m applying to it, otherwise it"ll fall through. Some forces are internal and some are external properties: Force will cause acceleration or deceleration if you apply a force to it.
