| Speed | Velocity |
| Speed is the distance travelled by an object in a given interval of time. It does not have any direction. | Velocity is the displacement of an object in a given interval of time. It has a unique direction. |
| The speed of an object can never be negative. At the most, it can become zero. This is because distance travelled can never be negative. | The velocity of an object can be negative, positive, or equal to zero. This is because displacement can take any of these three values.
|
Speed has only magnitude while velocity has both magnitude and direction. So speed is a scalar quantity but velocity is a vector quantity.

| Speed | Velocity |
| 1. Speed is a scalar quantity. | 1.Velocity is a vector quantity. |
| 2. Speed of a particle can be positive only. | 2. Velocity of a particle can be, positive, negative or zero. |
| 3. Speed is the time rate change of distance of a body. | 3. Velocity is the time rate change of displacement of a body. |
| 4. Speed tells nothing about the direction of the motion of the particle. | 4. Velocity tells the direction of motion of the particle. |
1. Speed is the rate of change of position of a body in any direction while velocity is the rate of change of position of a body in a particular direction.
2. Speed is a scalar quantity whereas velocity is a vector quantity
| Speed | Velocity |
|---|---|
| It indicates the rate at which objects move | It indicates the rate at which objects move and even direction of the object. |
1. Speed
- Speed is the distance traveled by an object in unit time
- Speed =\(\frac {\textit{distamce}}{\textit{time}} \)
- Speed is a scalar quantity
- Speed has only magnitude
2. Velocity
- Velocity is the rate of displacement of body in unit time.
- Velocity = \(\frac {\textit{displacement}}{\textit{time}} \)
- Velocity is a vector quantity
- It has both magnitude and direction.
