Motion and speed are related concepts but have distinct meanings:
Motion: Motion refers to the change in position of an object with respect to a reference point. It describes the overall movement or displacement of an object from one place to another. Motion can be described in terms of direction, distance, and time.
Speed: Speed, on the other hand, is a measure of how fast an object is moving. It specifically quantifies the rate at which an object changes its position. Speed is a scalar quantity, meaning it only has magnitude and not direction. It is calculated as the distance traveled divided by the time taken.
In simpler terms, motion describes the concept of an object being in motion or moving, whereas speed is a numerical measure of how quickly that object is moving. Motion is a broader concept that encompasses various aspects of an object's movement, including its speed, direction, and displacement.
