 Form 4 Physics Uniform Circular Motion Questions and Answers

a).Define the tem angular velocity.
b).A body moving with uniform angular velocity is found to have covered an angular distance of 170 radians in t seconds. Thirteen seconds later it is found to have covered a total distance of 300 radians .Determine t. c).Figure 8 shows a body of mass m attached to the centre of a rotating table with a string whose tension can be measured. The device for measuring tension is not shown in the figure).The tension on the string was measured for various values 0of angular velocity,w,.The distance r of the body from the centre was maintained at 30cm.
