Mean speed theorem
From Wikipedia, the free encyclopedia
Not to be confused with The Merton Rule.
The mean speed theorem, also known as the Merton rule of uniform acceleration,[1] was discovered in the 14th century by the Oxford Calculators of Merton College, and was proved by Nicole Oresme. It states that a uniformly accelerated body (starting from rest, i.e. zero initial velocity) travels the same distance as a body with uniform speed whose speed is half the final velocity of the accelerated body.[2]
