Define Tangential velocity.

What would be the change in tangential velocity of an electron, if it remains in same orbit and electronic charge is doubled ?

Orbital velocity V = sqrt((GM)/(R+h)) Suppose the orbit of a satellite is exactly 35780 km above the earth's surfce. Determine the tangential velocity of the satellite .

A uniform circular disc of radius R is rolling on a horizontal surface. Determine the tangential velocity : at the upper most point

Define : variable velocity

Define terminal velocity.
