Difference Between Speed And Velocity. Speed is the time rate at which an object is moving along a path while velocity is the rate and direction of an objects movement. In everyday usage the terms speed and velocity is often used interchangeably and it does not cause that much of a problem.
A cars speedometer can help you determine the difference between speed and velocity. The average velocity only depends on the starting and ending point not the path but the speed depends on the path in this definition. However speed is a scalar quantity which means that it can be described with a numerical value.
As against this velocity is a vector.
If the speed limit is 45 miles per hour it will read 45 miles per hour. Speed can never be zero but the velocity can be positive negative or zero. The road turns the shape does not matter only the ground covered. However speed is a scalar quantity which means that it can be described with a numerical value.
