Motion due to gravity
... The first person to state clearly that all objects on Earth fall with the same acceleration was Galileo (1564 − 1642). He used experimental observation with mathematical argument to arrive at this. This acceleration, denoted by the letter g, is known as the acceleration due to gravity. It has a valu ...
