The centripetal force is affected by mass, radius of the orbit, and angular velocity (related linearly to mass and radius but related to the square of angular velocity). Circular motion with speed v in a path of radius R has period (time for one revolution) T and frequency (revolutions/s) f = 1/ T . Since the object travels a distance 2 π R (the circumference of its circular path) in time T the speed v is equal to The purpose of this lab is to investigate the effect of mass on centripetal force using both measured and calculated values. Theory In the diagram at right, the apparatus rotates around the center of the blue force sensor, allowing the upwards direction to be noted as the radial, or positive, direction.

Clicking/tapping the hot spot opens the Interactive in full-screen mode. Use the Escape key on a keyboard (or comparable method) to exit from full-screen mode. There is a second hot-spot in the lower-right corner of the iFrame. 2016-06-30 · Centripetal force is essentially the net force action on an object moving in a circular path. Since the object is moving in circles around its axis of rotation, we can calculate its average angular velocity $(\bar{\omega})$ by dividing the total angular displacement $(\Delta \theta)$ by the total time $(\Delta t)$: direction toward the center of the circle if you wish to have circular motion.

Whether it's the back wall of the "Roundup" or "Rotor", PHYSICS 183 - LAB Experiment 3 Fall 2004 1 CENTRIPETAL FORCE & UNIFORM CIRCULAR MOTION In this experiment we will explore the relationship between force and acceleration for the case of uniform circular motion. An object which experiences a constant force The Circular Motion Lab Answer questions in complete sentences Introduction We have discussed motion in straight lines and parabolic arcs.

circular motion - anytime an object moves in a way that traces out a circular path. period (T) - the time it takes to go around a circle once.

and that the distance it took the wave to oscillate was 39 cm. Description.

Therefore the expression for the centripetal force can be written as: F = mv 2/r.
