Velocity is measured in meters/second in the S.I. system.
Power is energy / time, energy is power x time.This is similar to the distinction between distance and speed: speed = distance / time; at constant speed, distance = speed x time.Enery is measured in Joules, power is measured in Joules / second, a.k.a. "Watts".
motion is always measured in meters > uniform - constant - unchanging constant speed (SI units - metres per second)
Both the speed and the distance of distant galaxies must be measured accurately.
In science, a constant speed refers to an object moving at a uniform rate without accelerating or decelerating. This means that the object covers equal distances in equal intervals of time. Constant speed is typically measured in units such as meters per second or miles per hour.
Cavendish measured the gravitational constant "G".
The speed of light is a number. It was a theory before it was measured. After it was measured, and the prediction was found to be correct, it was no longer a theory nor a hypothesis. It became a "physical constant".
Hz (hertz) is a unit of frequency, not of speed.
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
Constant speed
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
Its is measured by speed,power,andwind speed
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
