What is Velocity?
Velocity is the rate of change of displacement of a body. It is used to determine the speed of an object in a particular direction. Velocity can be positive, negative or may be zero. Mathematically, it can derive as:
Velocity(v) = displacement(d)/time(t)
OR
V = d/t
- Velocity is a vector quantity as it has both magnitude and direction.
- SI unit of velocity is meter/second
Applications of Velocity
- Velocity provides the concept of an object’s motion, including both speed and direction.
- It provides the calculation of displacement.
- Velocity is very important in studying the laws of motion and understanding concepts like inertia and momentum.
- Velocity plays a very crucial role in various engineering disciplines such as aerospace, automotive, and civil engineering, for designing and optimizing motion systems.
Differences between Velocity and Acceleration
Velocity and acceleration are the two important terms that are related to physics. Velocity refers to the speed of an object in a particular direction whereas acceleration refers to the rate of change of velocity. Velocity and acceleration are both vector quantities as they have magnitude and direction, however, they have several differences.
In this article, we will learn about the velocity, acceleration, and the key differences between them.
