Newton's Laws (1) An object at rest or in motion in a straight line at a constant speed will remain in that state unless acted upon by a force. Newton's Laws (2) The acceleration of a body due to a force will be in the same direction as the force, with a magnitude directly proportional to its mass. Force = mass x acceleration (Smaller mass will move faster if same force is applied to it.) Newton's Laws (3) For every action, there is an equal and opposite reaction. Newton's Universal...

Galileo Galilei Created the first handmade telescope Galileo wasn't only interested in the beauty of nature however .... he wanted to know how nature worked. Galileo made observations using his telescope, which could magnify objects to more than .... 32 times their actual size. His observations and conclusions led to discoveries that intrigued and fascinated some people. Others were enraged because his findings ... contradicted the beliefs of the Catholic Church at that...

Diaphragm Part of the compound microscope used to regulate the amount of light being transmitted through the specimen on the slide. 1 milligram 1 x 10 -3 grams Kepler His greatest contribution to science was that he described the orbits of the planets as ellipses. Newton Used the 3 laws of planetary motion to establish universal gravitation.
