Newton discovered that gravity attracts any two objects depending on their . masses. and their . distance. .. Fg. is proportional to the two masses:. Fg. Objective: TSW understand, transfer and apply energy concepts to electric fields and charges by solving problems involving electric fields and forces.. Let’s revisit energy concepts for a gravitational field. A 250 gram baseball is thrown upward with an initial velocity of 25m/s. What is the maximum height reached by the ball?. some history. (based on D. . Kennefick’s. work). Historical tidbits. 1776: Laplace suggests four mechanisms that could explain secular perturbations of Moon-Earth orbit. One the explanations was a non-instantaneous propagation of gravity, affecting the binary system (abandoned because its speed would be too large to be measurable to explain the effect). .

IAU Comm.30, IAU XXVIII GA Beijing, August 2012. To help explain how two bodies that are not in contact can exert a force on one another (i.e. gravitational, magnetic or electrostatic) we use the concept of fields. .. Fields are spheres of influence. They are invisible and intangible; they simply demonstrate how strong a characteristic is at a certain distance.. Gravitational Waves. Prediction. General Relativity – 1915. Gravity is not the pulling force envisioned by Kepler or Newton. Space warps around massive objects. Accelerating massive objects could radiate distortions like the wake of a boat. D.S. . Hajdukovic. GBAR Collaboration Meeting. 18. th. April 2012. Our best physics .

Perhaps in contemplating the fall of an apple, Newton realized that its acceleration . was . a. Earth. = -9.81 m/s. 2. (. in . modern . metric terms).. He knew that the moon’s acceleration toward Earth was . Energy associated with forces that depend on the position or configuration of a body. Objects acquire potential energy when work is done on it. As an object loses potential energy, it can do work. Potential energy is the capacity to do work even if not doing work yet. Learning Objectives. I can mathematically rearrange the potential energy equation.. I can calculate Potential Energy using the formula.. Gravitational Potential Energy (GPE).
