Name the English gentleman who was responsible for the three laws of motion that serve as the foundation of classical physics. Sir isaac newton If you were able to let go of a ball in outer space, far away from the influence of gravity, without pushing it in any particular direction, what would happen? it would stay exactly where it was put. What would the force on your hand be from a book lying in your hand? The same amount of force applied to your hand from the book. How many decimeters are in one meter? 10 How many centimeters are in one meter 100 The farther an object falls under gravity the ____________ will be its velocity by the end of its travel greater Objects falling under the influence of gravity will fall with a constant acceleration Galileo, the Italian student of nature, lived in which century? 17th In its third second of fall, an object falling under gravity will fall at a velocity of (9.8 m/sec^2) times 3 = 29.4 m/sec^2 A ball thrown upward approaches its velocity when it reaches its highest point from the ground. lowest Two cannon balls of different masses, when dropped from the Leaning Tower of Pizza will hit the ground at the same time If an object having a mass of 1 gram were pushed so that it accelerated at a rate of 1 meter per second for each second of the push, what was the force of the push? 1 gram X 1 meter for every second of the fall the entire range of gravitational influence gravitional field a rate of increase or decrease in the rate of travel acceleration a ball, thrown upward, continues upward after it is released inertia a rate of travel velocity the natural force of attraction between any two masses gravity gravitational acceleration constant 9.8 meters/second ^2 a natural push or pull force From lessons 1-4
