What is the Difference Between Angular Velocity and Linear Velocity?
🆚 Go to Comparative Table 🆚The main difference between angular velocity and linear velocity lies in the way they describe the motion of an object. Here are the key differences:
- Linear Velocity: This refers to the speed of an object moving in a straight line, measured in meters per second (m/s). It is the rate of change of displacement with respect to time. Linear velocity is a vector quantity, meaning it has both magnitude and direction.
- Angular Velocity: This is the rate of change of the angular position of a rotating body, measured in radians per second (rad/s) or degrees per second (°/s). It describes how fast an object spins, rotates, or turns. Angular velocity is a vector quantity, as it has both magnitude and direction.
In summary, linear velocity is concerned with the motion of an object in a straight line, while angular velocity describes the rotational motion of an object.
Comparative Table: Angular Velocity vs Linear Velocity
Angular velocity and linear velocity are two different concepts in the context of motion and rotation. Here is a table highlighting the differences between them:
| Angular Velocity | Linear Velocity |
|---|---|
| Refers to the rate of change of an angle | Refers to the rate of change of linear displacement |
| Units are radians per second (rad/s) | Units are meters per second (m/s) or equivalent |
| Only two directions with respect to the axis of rotation: clockwise or counterclockwise | Tangent to the path of the object |
| Formula: $$\omega = \frac{\Delta\theta}{\Delta{t}}$$ | Formula: $$v = \frac{\Delta s}{\Delta{t}}$$ |
| Independent of the size of the circle or radius | Depends on the size of the circle or radius |
In summary, angular velocity describes the rate of change of an angle in a rotational motion, while linear velocity describes the rate of change of linear displacement in a straight-line motion. Angular velocity is independent of the size of the circle or radius, whereas linear velocity depends on it.
