Here’s are comparison between speed and velocity based on the given information:
Definition:
Speed: The rate of change of distance is called speed. It measures how quickly distance is covered.
Velocity: The rate of change of displacement is called velocity. It measures how quickly position changes and includes direction.
Quantity Type
Speed: A scalar quantity, which means it only has magnitude and no direction.
Velocity: A vector quantity, which means it has both magnitude and direction.
Direction of Motion:
Speed: Does not provide information about the direction of motion. It is only concerned with how fast an object is moving.
Velocity: Gives information about both the speed and the direction of motion.
Values:
Speed: Can be positive but cannot be negative or zero if the object is moving. For an object at rest, the speed is zero.
Velocity: Can be positive, negative, or zero, depending on the direction of motion relative to a chosen reference point. For example, velocity can be negative if the object moves in the opposite direction of the chosen positive direction.
Dependence on Direction:
Speed: Does not change with direction; it remains the same regardless of how the direction changes.
Velocity: Depends on direction; it changes if the direction of motion changes even if the speed remains constant.
In summary, speed measures how fast an object moves, regardless of direction, while velocity measures how fast and in which direction the object moves.
