# How to Calculate Relative Speed between Two Moving Objects?

When calculating the relative speed between two moving objects, it is important to consider their individual speeds and the direction in which they are moving. The relative speed is not simply the sum of their speeds, but rather the difference between their speeds.

## Understanding Relative Speed Calculation

Relative speed is the speed of an object in a particular reference frame. When two objects are moving with respect to each other, their relative speed can be calculated by finding the difference in their speeds.

For example, if object A is moving at 30 km/hr and object B is moving at 20 km/hr in the opposite direction, the relative speed between them would be the difference in their speeds, which is 10 km/hr (30 km/hr - 20 km/hr).

It is important to note that relative speed considers the motion of one object with respect to another. This means that the relative speed will vary depending on the direction of motion of the objects.

## Calculating Relative Speed Formula

The formula to calculate relative speed between two moving objects is:

**Relative Speed = | Speed of Object 1 - Speed of Object 2 |**

By using this formula, you can determine the relative speed between two objects moving in the same or opposite directions. Remember that the relative speed is always positive, as it represents the absolute difference in speeds between the objects.

Understanding how to calculate relative speed is essential in physics and everyday scenarios where objects are in motion relative to each other. With the correct approach, you can accurately determine the relative speed between moving objects.
