practice test-6-rotation-angular momentum
Torque, the “turning effect” produced by a Force applied to a moment-arm, is calculated according to , or , where is the angle between the vectors r and F. Here, each combination of wrench length and Force produces a net torque of LF except for answer c: € ω2=ω 0 2+2αθ α= ω 2−ω 0 2θ α= ω 2 2(2•2π) = ω 8π € P= W t W=ΔK ...
