Average velocity in a direction is calculated as the displacement in that direction divided by the total time taken. As the time interval is reduced, the displacement over that period also reduces and the limiting value of that ratio is the instantaneous velocity.

Velocity = Radius x RPM For example if a body of 32 Inches in diameter rotating at 3600 rpm, the velocity is calculated by Velocity = 32/2 * 3600 Velocity = 57,200 inches per minute Velocity = 57,200 Inches/min * 60 Min/Hr * 1ft/12in * 1 mi/5280 ft Velocity = 54.5 miles per hr

If I understand the question correctly.......... Average speed can be calculated by dividing displacement by time (scalar) but once you refer to direction and "velocity" you are into a different paradigm (vector) and it is not as simple as dividing displacement by time

The radial velocity ie velocity towards or away from your starting point. It is NOT the ordinary speed or velocity because you can run in a circle around your starting point at top speed but the distance will not change so the slope of the distance time graph will be zero.

Fo is calculated considering product pH, z- value and product residence time calculated considering safety factor of 0.8 to 0.5 to get average velocity. D. A. Nirhali IIT, Kharagpur

Orbital Velocity is calculated in m/s where as angular velocity is calculated in rad/s.. Answer is very clear.. angular velocity is calculated when body is rotating around a axis and a reference point is needed to calculate it.. where as orbital velocity is calculated when body is moving around a bado in circular path, nt around itself... e.g. Earth rotates around so it have angular velocity .. it also rotates around sun in orbit so it has Orbital velocity also :)

It is calculated as 1/2 mass multiplied by velocity squared

When you have calculated or measured it.

Velocity is displacement/time.

average velocity=displacement/total time taken

velocity.

it can be calculated at a particular instant as it is total displacement in given time

Velocity is defined asv = dx/dtwhere:v is velocity;dx is displacement;and dt is elapsed time.Assuming velocity is constant, then displacement is calculated as:dx = v/dt.
