This calculator will help you to solve all types of uniform acceleration problems.
As you may know, there are two main equations for uniform acceleration
Thus, we have five parameters of motion: initial velocity Vo, final velocity V, acceleration a, time t and displacement S, and two equations. Obvious conclusion - to use these equations we need three known parameters, and two unknown parameters.
As Combinatorics. Combinations, arrangements and permutations tells us, number of combination of 3 from 5 is 10, so, there are ten types of problems at all, each has different set of known parameters.
This calculator allows you to enter any three known parameters and use "-" symbol to denote unknown, and it kindly finds unknown ones. BTW, by default acceleration has value of gravity g, making a free fall problem
