What is velocity in physics?

Answer 1

Velocity is a vector quantity that describes the speed and direction that an object is moving. It is the same as "speed" except that it includes the direction of the object as well. Speed is the rate of change of distance.

Answer 2

Velocity is displacement over time. To understand this, you should know that displacement is the distance and direction from one point to another.

Let's say you walked 2 meters north, then 5 meters south. --> Your displacement would 3 meters south. Now say you walked all of that in 6 seconds. Your velocity would be (3 meters) / (6 seconds) = 0.5 m/s.

Note that if you were talking about distance and speed, you'd have walked 7 meters at an average of 7/6 m/s.

Answer 3

In addition to all the usual definitions such as "speed" and "quickness", the most accurate scientific definition is probably " the rate of change of position along a straight line with respect to time" or "the derivative of position with respect to time" as given by Webster's (and probably other) dictionaries.

Answer 4

The rate of displacement with respect to time is called velocity.It is vector quantity.

Answer 5

Velocity, in layman's terms, is speed in a direction.

If a car is moving at 50m/s, its speed is 50m/s.
If a car is moving at 50m/s to the left, its velocity is 50m/s left.
