The kinematic equations compose 4 equations that are used to hypothesize unknown information regarding the motion of an object if several variables are known. These equations can be used for any motion possessing either:
Given the above, they can never be used over a time period in which acceleration is changing.
Each kinematic equation is composed of 4 variables. In the event that the values of 3 out of the 4 variables are known, then the value of the 4th can be properly calculated.
The kinematic equations are as follows:
