Here's a breakdown:

* Change in position: This means an object is moving from one location to another.

* Over time: Motion happens over a certain duration, even if it's very short.

We can describe motion using various concepts:

* Displacement: The straight-line distance and direction between an object's starting and ending points.

* Distance: The total length of the path traveled by an object.

* Speed: How quickly an object is moving (distance traveled per unit time).

* Velocity: The rate at which an object changes its position, considering both speed and direction.

* Acceleration: The rate at which an object's velocity changes over time.

So, motion isn't just about movement itself, but also about how that movement happens.
