Torricelli's equation is an equation created by Evangelista Torricelli to find the final velocity of an object moving with a constant acceleration without having a known time interval.
The equation itself is:
Derivation
Begin with the equation for velocity:
Square both sides to get:
The term appears in the equation for displacement, and can be isolated:
Substituting this back into our original equation yields:
