Answer
Imagine you're sitting in a moving car. When you look around, you feel like you're not moving because everything inside the car seems still. This feeling is called "rest" because you feel like you're not going anywhere
But if someone is standing outside watching the car go by, they see you moving along with the car. From their perspective, you're not at rest; you're in "motion."
So, whether something is at rest or in motion depends on who is looking at it. That's why we say rest and motion are relative terms – they depend on the observer's point of view.
In everyday life, it's like when you're on a bus, and you see buildings moving past you. You're moving concerning the buildings, but you feel like you're at rest inside the bus because you're moving together with it.
This idea might seem simple, but it's essential in understanding how motion works, especially when we talk about things like cars, trains, or even planets moving in space.
