WebJan 15, 2024 · We start with the first constant angular acceleration equation (equation 19A.3 ): θ = 0 + 0 ⋅ t + 1 2 ∝ t2 The initial angular velocity ω0 is given as zero. We have defined the initial angular position to be zero. This means that, at time t = 2.00s, the angular position θ is 15.0rev = 15.0 rev2π rad rev = 94.25rad. Web(Here and elsewhere, if motion is in a straight line, vector quantities can be substituted by scalars in the equations.). By the fundamental theorem of calculus, it can be seen that the integral of the acceleration function a(t) is the velocity function v(t); that is, the area under the curve of an acceleration vs. time (a vs. t) graph corresponds to the change of velocity.
