SUVAT is an acronym of the five variables in physics which play crucial rule in-laws of motion and newton mechanics that describe a system in motion with constant acceleration: displacement s, initial velocity u, final velocity v, acceleration a, and time t in a given frame of space.
SUVAT Calculator: The calculator developed by us will help you solve the equations related to laws of motion, straight-line motions, and even mechanics questions based on this with accuracy and efficiency. All you have to do is simply provide the corresponding inputs in the input fields and then click on the calculate button to avail the output in no time.
The major SUVAT formulas describe all most all the things in motion on a uniform platform or a straight line, as long it is driven by uniform acceleration. The first equation of SUVAT in terms of velocity is v = u + at
The second equation of motion of SUVAT is as follows: s = 1/2(u + u + at) * t, (this equation is used to determine the displacement of the object covered)
And for the object which starts from rest with a constant velocity throughout its motion under the constant force. s = ut + 1/2 at2.
The last and the third equation of motion and SUVAT is slightly complex and it is made by adding the first two equations of the motion. s = 1/2(u + v)((v - u) / a)
The SUVAT calculator works on the principle of the laws of motion in a straight line or in a plane, to solve the questions related to this the user needs to do the following
Question 1: A bus starting from rest moves with a uniform acceleration of 0.1 ms-2 for 2 minutes. Find the speed acquired and the distance traveled by bus
Solution:
Given:
The bus starts from rest and then moves with a uniform acceleration of 0.1 m/s² for 2 following minutes
The bus starts from rest and hence we can consider its initial velocity (u) is 0 m/s
The Acceleration (a) of bus is given as = 0.1 m/s²
Time is given as = 2 minutes which means 120 s
Acceleration is given by the equation a=(v-u)/t
Therefore, terminal velocity (v) by the first law of SUVAT = (at)+u
Substituting the values we get, 12m/s
Since it is solved as that a = 0.1 m/s², v = 12 m/s, u = 0 m/s, and t = 120s, the following value for s (distance) can be obtained.
Therefore, s = 720 m.
The speed acquired by bus is 12 m/s and the total distance traveled by it is 720 m.
Question 2: A train is traveling at a speed of 90 km/h. Brakes are applied so as to produce a uniform acceleration of –0.5 m/s². Find how far the train will go before it is brought to rest?
Solution:
Given:
The initial velocity (u) of the train= 90 km/hour which can be converted as 25 m/s
The Terminal velocity (v) of the train is 0 m/s as sudden brakes are applied.
The Acceleration of the train is (a) = -0.5 m/s²
As per the third equation of motion law Formula
(v²-u²) = 2as
And hence we can say that,
The distance travelled by train (s) =(v²-u²)/2a
On substituting the known values in this equation, we get
= 625 meters
And hence the train must travel 625 meters at an acceleration of -0.5 m/s² before it reaches the rest position by applying the brakes.

1. What is the difference between the ‘v’ and ‘u’ in the equation of the motion?
‘U’ stands for the initial velocity of the object and ‘v’ stands for the final velocity of the object.
2. What is the equation for SUVAT?
The full set of SUVAT equations that one should commit to their memory are V = U + A T. S = ( U + V 2 ) T.
3. How do you calculate acceleration using SUVAT?
You can find acceleration using SUVAT from the formula v= u+at. Rewriting this formula you can obtain the acceleration.
4. How do you calculate displacement using SUVAT?
s = ut + 1/2at² can be used to calculate displacement using SUVAT.
5. When can you use SUVAT?
The SUVAT equations are used when acceleration is constant and velocity is changing in a body that is moving.
