WebIntroduction. Everyone has a good intuitive notion of the relation between position and speed of motion of a moving object. This relation is an example of the notion of derivative. … WebIn simple words, velocity is a measure of how much time an object takes to reach a destination with direction. Moreover, it is directly related to displacement and inversely relates to the time traveled. Also, its unit is meter per second (m/s). Velocity formula = displacement ÷ time

WebThe reason is simple. 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. For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west ...
