Rest and motion are concepts used to describe the state of an object in relation to its position and movement.
1. **Rest:**
- Rest refers to the state in which an object remains stationary or motionless.
- An object is considered to be at rest when its position does not change with respect to its surroundings.
- For example, a book lying on a table is at rest as long as it doesn't change its position relative to the table.
2. **Motion:**
- Motion refers to the change in position of an object over time.
- An object is said to be in motion if its position changes concerning its surroundings.
- Motion can be described in terms of speed, direction, and displacement.
- For instance, a car moving along a road is an example of motion.
These concepts are relative, meaning that an object can be at rest or in motion depending on the observer's frame of reference. What might appear stationary to one observer might seem to be in motion to another who is moving relative to the first observer.
Understanding rest and motion is fundamental in physics, as they are crucial in describing the behavior of objects and the principles governing their interactions with forces and energy.

Answer:
When do we say that a body is at rest and when do we say that it is in motion.
If a body does not change its position as time passes it is all rest. If a body changes its position with time, it is said to be moving.
