You can transform linear velocity into rotational velocity with a rolling wheel.
Rotational velocity can be measured inside a gravity field because of generated centrifugal force. When you suspend your arms freely while rotating, the angle between your body and your arm is a measure for the rotational speed.

What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
Does the speedometerof a car read average speed or instantaneous speed?
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
What type of velocity does the speedometer on a car measure?
It reads instantaneous speed, and tells you nothing about average speed.
Is instantaneous velocity a vector or a scalar?
Velocity is always a scalar, instantaneous or average doesn't matter.
What is a instantaneous velocity?
Instantaneous velocity: The velocity of an object at one moment in time.
What measure instantaneous speed?
Your speedometer! It tells you how fast you are going at that instant.All different types of devices are used to measure instantaneous velocity including chronographs, lasers, and radars.
Does the speedometerof a car read average speed or instantaneous speed?
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
What is the Instantaneous velocity?
Instantaneous velocity is the velocity in difference displacement in shortest time or specific time interval.
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
What type of velocity does the speedometer on a car measure?
It reads instantaneous speed, and tells you nothing about average speed.
Does light speed accelerate or is it instantaneous velocity?
Instantaneous.
Is instantaneous velocity a vector or a scalar?
Velocity is always a scalar, instantaneous or average doesn't matter.
What does a tangent to a velocity-time graph measure?
It will measure acceleration in the direction towards or away from the origin.
What Is the difference between velocity and average velocity?
Velocity is an instantaneous measure. Mathematically, it is the limiting value of the change in the position vector divided by the change in time as the latter tends to zero. Over larger time periods, the average velocity is the total change in the position vector divided by the total change in time. If velocity is constant, the average velocity will be the same as the instantaneous velocity.
Does the slope of a position time graph represent average velocity or rate of change of velocity?
The tangent at a point on the position-time graph represents the instantaneous velocity. 1. The tangent is the instantaneous slope. 2. Rather than "average" velocity, the slope gives you "instantaneous" velocity. The average of the instantaneous gives you average velocity.
When is the instantaneous velocity equal to avg velocity?
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
