Short Answer
Relative motion means the motion of one object compared to another. In real life, we see many examples of this, such as vehicles moving on roads, trains crossing each other, and people walking in different directions.
For example, when two cars move towards each other, they appear to move faster relative to one another. Similarly, when one car overtakes another, their motion is observed relative to each other.
Detailed Explanation:
Real-life examples of relative motion
Relative motion is a concept that helps us understand how objects move in relation to each other. In real life, motion is rarely observed in isolation. Instead, we usually compare the movement of one object with another. This comparison helps us understand how fast objects are approaching, moving away, or moving together.
Relative motion depends on the position and movement of both objects. If one object is stationary and another is moving, the motion is observed relative to the stationary object. If both objects are moving, their motion is compared to find how they behave with respect to each other. This concept is very useful in daily life and helps in solving motion-related problems easily.
- Vehicles on roads
One of the most common examples of relative motion is vehicles moving on roads. When two cars move in the same direction, one car may slowly overtake the other. From the point of view of the faster car, the slower car appears to move backward. Similarly, if two cars move in opposite directions, they appear to pass each other very quickly.
- Trains crossing each other
When two trains move in opposite directions, they cross each other quickly. This is because their relative speed is high. If they move in the same direction, one train may slowly overtake the other. This is a clear example of relative motion in daily life.
- Person inside a moving vehicle
A person sitting inside a moving bus may appear to be at rest to another passenger in the same bus. However, to a person standing outside, the same person is moving along with the bus. This shows that motion depends on the observer and is relative.
- Walking on a moving walkway
At airports, people walk on moving walkways. If a person walks in the same direction as the walkway, their speed increases relative to the ground. If they walk in the opposite direction, their speed decreases. This is another example of relative motion.
- Boats in a river
When a boat moves in a flowing river, its motion is affected by the flow of water. The boat’s speed relative to the water and relative to the ground is different. This is a practical example of relative motion.
- Airplanes and wind
An airplane flying in the air is affected by wind. The speed of the airplane relative to the air and relative to the ground can be different. This concept is used in aviation to calculate travel time and direction.
Importance of real-life examples

Conclusion
Relative motion is an important concept that helps us understand how objects move in relation to each other. Real-life examples like vehicles, trains, and moving walkways make it easy to understand and apply this concept in daily life and problem-solving.
