Distinguish between speed and velocity:
Answers
Explanation:
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. Put another way, speed is a scalar value, while velocity is a vector. ... In its simplest form, average velocity is calculated by dividing change in position (Δr) by change in time (Δt).
1. Speed is the distance moved by an object over a time interval. Speed does not have any directions only magnitude, hence speed is a scalar quantity. Speed cannot hold any kind of negative value. It may or may not be equal to velocity. Speed in standard unit measured as ms-1.
2. Velocity is the displacement of a given object over a time interval. Velocity has direction and magnitude both, hence it is a vector quantity. Velocity can hold negative value. In case of velocity, a body mass possesses different velocities but at the same speed. Velocity i standard unit measured s ms-1.
