Document Summary
How things move in a circle, how things rotate, what you see, position displacement velocity when things move around a circle. Draws an object to center of rotation. Object wants to stay in certain path unless force acts upon it. If all three are larger it creates more centripetal force. Has the same magnitude and dimensions but in opposite direction. Forces act in ways that come in different shapes forms and sizes. Wind resistance, fluid drag (amount of force created by wind) Centripetal, pulls toward an axis of rotation. Centrifugal, pulls away from an axis of rotation. Force arm is measured in m, amount of distance between force application and pivot. Big torque= increase in force generated, or increase in force arm. Properties of a force: magnitude, direction, point of application, line of action. Shortest distance from axis of rotation to the line of action of the applied force.
