Tangential Speed is equal to the instantaneous linear speed of the particle at any point on the curved path. Tangential speed at any point is equal to the multiplication of the radius of curvature and angular speed at a particular point on the curved path. Angular speed is defined as the time rate of change of the angular displacement along the curved path.
The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is 7008299792458000000â 299,792,458 metres per second. It is exact because the unit of length, the metre, is defined from this constant and the international standard for time. According to special relativity, c is the maximum speed at which all conventional matter and hence all known forms of information in the universe can travel. Though this speed is most ...
