Question

Define Velocity and its unit ! ​

Answer 1

Answer:

Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude.

Answer 2

Answer:

Velocity is defined as the rate of change of displacement of a body with respect to time. Its unit in SI is m/s.

Velocity is defined as the rate of change of displacement of a body with respect to time. Its unit in SI is m/s.Velocity is a vector quantity that refers to the rate at which an object changes its position. It is a vector expression of the displacement that an object or particle undergoes with respect to time.

Velocity is defined as the rate of change of distance of the body with respect to time. Its unit in SI is km/s. ... Velocity is defined as the rate of change of displacement of the body with respect to time. Its unit in SI is m/s. Velocity: Velocity is the speed of an object moving in a definite direction. The SI unit of velocity is also metre per second. 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. The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated but velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. The SI unit of it is meter per second (ms-1). If there is a change in magnitude or the direction in the velocity of a body the body is said to be accelerating.
