Velocity Ratio (VR) is a concept from machines in physics.

Definition

Velocity Ratio is the ratio of the distance moved by the effort to the distance moved by the load.

VR = frac{text{Distance moved by effort}}{text{Distance moved by load}}

Explanation

It shows how many times the effort moves compared to the load in a machine.

For example:

• If the effort moves 4 m
• And the load moves 1 m

VR = frac{4}{1} = 4

So the velocity ratio = 4.

Simple Meaning

Velocity ratio tells us how much the machine multiplies the movement.

Important

• It does not depend on friction
• It depends only on the design of the machine

boxed{VR = frac{text{distance moved by effort}}{text{distance moved by load}}}
