WebMay 23, 2015 · A mass is attached to a rope, and put into a circular motion. If I pull the string from the center, the tangential speed of the mass will increase (by conservation of angular momentum). I am applying a force only in the radial direction, so how can the tangential velocity increase if there is no tangential force? WebThe linear velocity is the same as the tangential velocity. ... The velocity ratio of a pair of internal gears can be either positive or negative. The velocity ratio of a pair of internal gears will always be 1:1. None of these. 19 Which of the following statements is NOT true about a linear displacement of a point on a link?

WebAug 31, 2024 · In circular motion, velocity is actually the same as tangential velocity, or in other words, there is no radial component of the velocity (otherwise it wouldn't describe a circle). Now, a force produces … WebNote that the v v s in these formulas refer to the magnitudes of the total velocity vector, the total speed, and can therefore never be negative.
