# Definition:Polar Vector

## Definition

A polar vector is a vector quantity whose action is along a line drawn in the direction of the vector itself.

## Examples

### Force

Force is an example of a polar vector.

It is applied along a line of action or at a point of action and so induces acceleration in the direction of that force.

### Displacement

Displacement is an example of a polar vector.

It is the result of motion in a particular direction defined by the vector representing that displacement.

### Velocity

Velocity is an example of a polar vector.

It is defined as motion in a particular direction defined by the vector representing that velocity.
