PHYS 1010 Newton’s Laws—Laws to explain motion 1 st law—an object at rest will remain at rest; an object moving in a direction at a constant speed will remain at that speed and at that direction o Velocity Speed Direction o This law was actually first realized by Galileo He called it inertia; inertia has a Latin origin, and basically means inactive o Basically this law is just saying that objects will keep on doing what they are doing o It is force that is required to stop the motion; absence of force would just mean the object keeps moving per Newton’s force law. Force isn’t need to put something in motion, but needed to stop it. o Change in velocity=acceleration 2 nd law o Greater force greater acceleration o Greater mass smaller acceleration A * F A* 1/M o Mass= amount of matter in object o Weight=gravity acting on mass o Force=mass*acceleration o A=g (acceleration=acceleration of gravity) If there’s NO air resistance a=F/M

Unformatted text preview: 3 rd law o For every force there’s an equal and opposite force Kepler’s law Ptolemy Retrograde motion Eccentricity—stretching the a round shape (Circle ellipse) Kepler’s First Law: The orbits of the planets are ellipses, with the Sun at one focus of the ellipse. Kepler’s Second Law: The line joining the planet to the Sun sweeps out equal areas in equal times as the planet travels around the ellipse Kepler’s Third Law: Newton’s Law of Gravitation Conservation of Angular Momentum Conservation of Energy Conservation of Momentum Energy—Quantity often understood as the ability to do work Forms of energy: Mechanical energy-1. Kinetic energy Definition of Simple Harmonic Motion (SHM): Periodic motion about an equilibrium position in a sinusoidal pattern. A body in SHM experiences an opposing or correcting force proportional to displacement and in opposite direction to motion....
