average speed (v) =
type of speed\tdescription\texample
instantaneous
average
constant

Explanation:

Motion refers to the change in position of an object over time. Distance is the total length of the path traveled by an object. Displacement is the straight - line distance from the initial to the final position with direction. Speed is the rate of change of distance. Average speed (v) is calculated as the total distance traveled divided by the total time taken, i.e., $v=\frac{\text{total distance}}{\text{total time}}$. Instantaneous speed is the speed of an object at a particular instant. Average speed is the overall rate of motion over a period of time (e.g., a car travels 100 km in 2 hours, average speed is 50 km/h). Constant speed means the speed of an object does not change over time (e.g., a car moving at a steady 60 km/h on a highway).

Answer:

Motion - Change in position over time
Distance - Total path length
Displacement - Straight - line distance with direction
Speed - Rate of change of distance
Average speed (v) = $\frac{\text{total distance}}{\text{total time}}$
Instantaneous - Speed at a particular instant
Average - Overall rate of motion over time (e.g., car travels 100 km in 2 h, avg speed 50 km/h)
Constant - Unchanging speed (e.g., car moving at steady 60 km/h)
