Is it true or false that Galileo believe that the natural state of an object was to be at rest?
if the forces acting on an object are balanced the object may change speed change direction or do both true or false?
Danish astronomer, Olaus Roemer, was the first person to successfully measure the speed of light in 1676. He based his observations on the eclipses of the moons of Jupiter. Many believe Galileo was the first to measure light, but this is false. Galileo tried, but his experiment failed to provide a correct calculation.
