Physics Calculators ▶ Kinematics Calculator
An online kinematics calculator that uses the equations of motion to solve motion calculations that involves the constant acceleration in a straight line. This kinematic equations solver determines the results for the initial, final velocity, displacement & time. In physics, the kinematics refers to the branch in which we study the motion of object without any force which causes the motion. Read on to completely know about the kinematic equations physics, how to find the unknown manually and much more. But ahead to some basics.
Also, you can try our online velocity calculator that helps you to find the velocity of the moving object corresponding to the different calculation parameters.

The equations of motion relate the five variables that are listed below:
For the calculation of time between the two different times or dates, try an online time calculator for the exact calculations of the time. Our kinematic equations calculator uses the following three equations to find the unknown variables:
Where,
v & u are the initial and final velocities respectively and a is constant acceleration S is the displacement. For ease, you can also use our online acceleration calculator for the calculations of the acceleration of the moving object from the different calculation formulas.
The calculations for the moving object become very easy with this tool. Here we have some manual examples. After reading, you will be able to completely solve different kinematics equations:

Example 1:
An object start with the velocity of 2ms-1 , after 8seconds attains the velocity of 30ms-1. Determine the acceleration and the distance covered by the object?
Solution:
Here,
\(u = 2 ms^{-1}\)
\(v = 30 ms^{-1}\)
\(t = 8s\)
So,
By first equation of motion:
\(v = u + at\)
\(30 = 2 + a(8)\)
\(30-2 = 8a\)
\(28 = 8a\)
\(a = 28/8\)
\(a = 3.5ms^{-12}\)
Now, using second equation of motion:
\(S = ut + ½ at^{2}\)
\(S = (2)(8) + ½ (3.5)(8)^{2}\)
\(S = 16 + ½ (3.5)(64)\)
\(S = 16 + ½ (224)\)
\(S = 16 +112\)
\(S = 128m\)
Example 2:
A body moves with an acceleration of 4ms-2 in 14s and covers a displacement of 40m. Find the initial & final velocity of the body?
Solution:
Here,
\(a = 4ms^{-2}\)
\(t = 14s\)
\(S = 40m\)
From the second equation of motion:
\(S = ut + ½ at^{2}\)
\(u = S – ½ at^{2} / t \)
\(u = 40 – ½ (4)(14)^{2}/ 14\)
\(u = 40 – ½ (4)(196) / 14\)
\(u = 40 – (0.5) (4)(196) / 14\)
\(u = 40 – 392 / 14\)
\(u =– 352 / 14\)
\(u = -25.14ms^{-1}\)
Now, using first equation:
\(v = u + at\)
\(v = -25.14 + 4*14\)
\(v = -25.14 + 56\)
\(v = 30.85ms^{-1}\)
It can be solve for the simple & easy data, when it comes to do the calculations for the complex data, then our kinematic calculator helps you to do the calculations for simple as well as complex data set.
Calculations become very easy for any variable in the equation of motion with the help of this tool. Our calculator determines the two variables given three variables as following:
Just stick to the following steps for the exact calculation for any of two variables:

Once you fill all the fields, the calculator shows:
Note:
No matter, what’s your input is, the kinematics calculator shows you the outcomes according to your selected input parameters.
The acceleration is the rate of change of velocity of a moving object. Simply, dividing the velocity with the time taken by an object gives the acceleration of the object.
Kinematic variables including position, velocity & acceleration of body can be used to describe the state of rest or motion of the body. They are used in many real life fields like in mechanical engineering, biomechanics and robotics to describe the motion of engine, skeleton of human body or robot. So, to solve the kinematics formulas for any of the variable, you can try this online kinematics calculator that helps you to do the calculations for the state of the moving object accurately.
