Document Summary

Motio(cid:374): the (cid:272)ha(cid:374)ge of a(cid:374) o(cid:271)je(cid:272)t"s positio(cid:374) o(cid:396) o(cid:396)ie(cid:374)tatio(cid:374) (cid:449)ith ti(cid:373)e. Trajectory: the path along which an object moves. 4 basic types of motion are straight line motion (car going straight), circular motion (race track), projectile motion (shooting basketball in a hoop), and rotational motion (bay blade). Easy way to study motion is to record a video of a moving object with a stationary camera. Video camera takes 30 images every second; each separate image is called a frame. Motio(cid:374) diag(cid:396)a(cid:373): o(cid:271)je(cid:272)t"s positio(cid:374) at se(cid:448)e(cid:396)al e(cid:395)ual spa(cid:272)ed i(cid:374)sta(cid:374)ts of ti(cid:373)e. Operational definitions: concepts are defined in terms of a particular procedure or operation (constant speed, speeding up, slowing down) Particle: an object represented as a mass at a single point in space. Model: treating an object as a particle is a simplification (model) of reality. Particle model: simplification in which we treat a moving object as if all of its mass were concentrated at a single point.
