Answer:
1. A body is said to be in a state of motion when it is moving or equivalently its position continuously changes with respect to time.
2. Average velocity and average speed are not always the same as average velocity is related to the displacement of a body whereas average speed is related to the distance travelled by a body. Average velocity is determined by dividing the total displacement of a body with time.
3. To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed. We use a small distance of the trip.
