Velocity is the general speed of an object in a دیا direction. Basically, that is the most general definition, so I'll go into مزید detail. Velocity is different to speed and acceleration. Acceleration is the mechanism of a car gaining speed, while speed is the rate of change, in position, of the object itself. A vector is the direction that the object is heading in and deals with any changes to the object's direction. Velocity deals with all of these, as it revolves around the object moving in a direction, as well as the دیا speed of کہا object. For example, if a car is travelling at a speed of 100 km/hour, the car's speed has been specified... If a car is travelling at 80 km/hour, due north, then its velocity has also been specified. I'll quickly touch on constant velocity. When an object reaches a certain speed, while being acted upon سے طرف کی the forces of gravity, that object cannot change its speed. This would be true if someone were to go skydiving, where forces of gravity are acting upon the skydiver's body and keeping them from slowing down, as they jump out of the plane at a certain speed and then keep gaining speed, as they are falling. This is what is known as constant velocity, as the skydiver is remaining at a constant velocity, from the initial speed and the forces of gravity, یا gravitational energy.
