By the end of this unit, a successful student will be able to:
- (9) Describe conceptually the forces involved in circular motion (MSTE: Phys 1.8)
- (9) Understand centripetal acceleration, its relationship to speed, radial and circumferential distances, and central forces and solve problems using those relationships.
- (12.4-12.6) Describe Newton’s Law of Universal Gravitation in terms of the attraction between two objects, their masses, and the distance between them (MSTE: Phys 1.7)
- Use mathematical representations of Newton’s Law of Gravitation to describe and predict the gravitational forces between objects (NGSS HS-PS2-4)
- (12.4-12.6) Use Newton’s law of universal gravitation to solve problems.

- Suggesting that there might be a law of conservation of great physicists, Isaac Newton was born in the year Galileo died. Newton (1642-1713) assembled the basis of much of classical mechanics in his Mathematical Principles of Natural Philosophy (1687) other copies can be found here and here and here wherein he decribes the relationships between forces, mass and acceleration as well as describes the nature of the force of univeral gravitation. All of these are English translations of the original Latin Principia. Newton was notorious for developing his briliant ideas about mathematics and physics and then not publishing them until much later. Many of the concepts embeded in the Principia were developed by Newton while away from Cambridge during the plague years of 1665-1666. His reticence to publish earlier helped lead to a number of conflicts concerning priority between Newton and his contemporaries such as Leibnitz, Hooke, and Huygens.
