WebFeb 20, 2024 · How fast is an object rotating? We define angular velocity ω as the rate of change of an angle. In symbols, this is (6.1.6) ω = Δ θ Δ t, where an angular rotation Δ θ takes place in a time Δ t. The greater the rotation angle in a given amount of time, the greater the angular velocity. WebCentripetal force (F) and time period (T) of a rotating object of mass m in a circle of radius r is related by equation F=m*4* pi^2*T* (17T^2). If the radius r of the circle is 1.5 m. pi = 3.14 and F vs 1/(T)^2 plot produces a slope of 3.0 N.s^2, then the mass of the rotating object is O a 0.03 kg O b. 1.10 kg O c. 0.05 kg O d. 0.11 kg
