The 6d. loaf weighs 3J Ibs., when wheat is 50s. a quarter; what will it weigh,...1000 feet, supposing that the velocity obtained in 2J- seconds is 80-5 feet. 38. The lengths of the arms of a lever are inversely proportional to the...

...traces its own curve of movement on a revolving cylinder. The investigations in question demonstrate that the velocity of a falling body is proportional to the time during which the motion has lasted. It increases in an arithmetical ratio or progression. At the end of the first...

...Since the frets AF occur at equal time intervals, the above computation supports Galileo's assertion that the velocity of a falling body is proportional to the time elapsed since the rest position. Start Middle End If Galileo and Fermat had had some further discussions,...
