Question

when we sitting on the school bus on your way to school are you at rest or in motion explain

Answer 1

It all depends on the frame of reference of the observer.

If the observer is in the bus, their frame of reference is the bus. Relative to them, you’re motionless, whether the bus is moving or not.

If the observer is standing by the side of the road and the bus is moving past them, their frame of reference is the road, and you’re in motion relative to them.

If the observer is in another bus, their frame of reference is the other bus - and depending on whether it is moving at the same speed as your bus or not, you might be in motion or relatively stationary.

Einstein had a lot to say about all that, and light. Relativity is fascinating.

Answer 2

both rest and motion
we are in motion with respect to road and surroundings
we are in rest with respect to the seat of bus
