Question

Hey !!! everyone, hope you're doing well. Difine velocity.✌️✌️​

Answer 1

Answer:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion

I hope it is helpful

Answer 2

Explanation:

The terms velocity and speed give us an idea of how fast or slow an object is moving. Quite often, we come across situations where we need to identify which of the two or more objects is moving faster. One can easily tell the faster of the two if they are moving in the same direction on the same road. However, if their direction of motion is in the opposite direction, then it is difficult to determine the fastest. In such cases, the concept of velocity is helpful, which we shall be discussing in this article.

What is Velocity?

The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect

The above graph is a graph of displacement versus time for a body moving with constant velocity. The straight line in the graph can be algebraically represented as follows:

x=x0+vt In the equation, x0 is the displacement at time t, v is the constant velocity of the body v=dxdt.

Velocity Units

The SI unit of velocity is m/s (m⋅s−1). Other units and dimensions of velocity are given in the table below.
