The net force is the in the direction of the motion, since the direction of the motion is positive the force must be positive, to do this we will take the absolute value of the gravitational force. hbspt.cta.load(360031, '4efd5fbd-40d7-4b12-8674-6c4f312edd05', {}); Have any questions about this article or other topics? Where, The faster the tire spins, the faster the car moveslarge No, because tangential speed is independent of the radius. Swing the object around in a horizontal circle above your head (swing from your wrist). When objects rotate about some axisfor example, when the CD in Figure 6.2 rotates about its centereach point in the object follows a circular path. $$. The total acceleration on the block is {eq}1.122\ \mathrm{m/s^2} Equate the total force from Step 3 to mass times acceleration and solve for the acceleration. t Repeat steps 25, Move your hand up the string so that its length is 50 cm. WebAnswer (1 of 3): There are so many questions similar to this on Quora. Positive motion is measured in a counterclockwise direction. A compact disc plays in the machine by rotating at an angular velocity of 160 radians per second.
