Activity: Rotational KE

IB Physics: Activity: Rotational KE

Consider a particle rotating on the end of a massless rod.If a body is made of a large number of small particles thenConsider a small displacement Δs (so small that the motion can be considered linear).If the angle is measured in radians Δθ = Δs/rExampleA force of 100 N is applied to the rim of a solid disk as shown.If the disk starts at rest calculate
