Everyone is aware of velocity, but there is a common misunderstanding about it. It’s a common misconception that speed and velocity are interchangeable, but the truth is quite the opposite. Additionally, the majority of people use them interchangeably and consider them to be synonymous. Moreover, despite being quite similar, they are not the same. The Velocity Formula is discussed in this article. Velocity Formula is an extremely important part of Physics.
It speaks of the speed at which the displacement changes in relation to time. Furthermore, the two main components of velocity are distance and displacement. Additionally, there won’t be any velocity if the object doesn’t move and there isn’t any displacement in its portion.
What distinguishes displacement from distance, then? The term “displacement” describes the overall shift in an object’s position while it is moving. On the other hand, distance describes the amount of space a moving object covers.
Distance is also a scalar quantity because it can be described solely in terms of magnitude and has no connection to direction. Displacement, on the other hand, is a vector quantity because its magnitude and direction are both fully described. Additionally, velocity is a vector quantity and a function of displacement.
Let’s now examine the Velocity Formula. Velocity is a change in an object’s displacement over time, as was previously discussed. Simply put, velocity is a measurement of the amount of time it takes an object to move in a particular direction. Additionally, it has an inverse relationship with time travelled and a direct relationship with displacement. Its measurement is in metres per second (m/s).
Velocity Formula = displacement ÷ time
Displacement = final position – initial position or change in position
Time = taken to cover the distance.
Now let’s take some values to understand the formula clearly. Suppose Mr. X initial position is ai and his final position is af and he has taken t time to cover this distance then the equation will be.
v = af – ai / t = a / t
v = velocity which is m/s (meter per second)
af = final position of X
ai = initial position of X
t = time taken by the object to move along the distance (s)
a =change in position (final – initial) (m)
Solved Example on Velocity Formula
Delivering solutions requires the Velocity Formula. It is advisable for students to practise answering inquiries about the Velocity Formula. With the help of Extramarks, you can fully practise each one of them. Students can assess their strengths and weaknesses with the help of a solid understanding of the Velocity Formula. Exam preparation can be aided by the Velocity Formula. It can be difficult to remember formulas at times. In order to aid students in learning and comprehending the Velocity Formula, these solved examples have been carefully chosen. The example given below is based on Velocity Formula.
Example 1- Suppose there is an object travelling a distance of 10 meters in the left direction and the time taken by the object is 2 minutes. Find the velocity of the object.
Now recall the formula which is velocity = displacement ÷ time
v = a / t
Now put the values in the formula. But first of all change minutes into time by multiplying minutes by 60.
Time in seconds = time in minutes × number of seconds in a minute
ts = 2 × 60 = 120 s
So, time in seconds is 120 s
v = 10 / 120
v = 0.08 m/s
The velocity of the object is 0.08 m/s.
