PPT-Isaac Newton and Gravity

An Invisible Force Gravity Every object pulls on every other object with an invisible force called gravity There is gravity between you and your toy car but you wont notice it because it is so weak. 1 = 8.85 32 = 283.22 63 = 557.60 94 = 831.97 125 = 1106.34 2 = 17.70 33 = 292.07 64 = 566.45 95 = 840.82 126 = 1115.19 3 = 26.55 34 = 300.93 65 = 575.30 96 = 849.67 127 = 1124.04 4 = 35.40 35 = 309.78 Einstein and Newton. 1. Newtonian Gravity. Newton explains the universe using forces. 2. Newton. Newtonian gravitational theory is based on forces acting on one another.. An object at rest stays at rest and an object in motion stays in motion (in a straight line) until acted upon by another force.. Laws of Motion. November 2011. Sir Isaac Newton. 1. Described 3 laws that relate forces to motion. 2. . Force. -a push or a pull, all forces have size and direction. Vocabulary. 1. . Friction. - a force that opposes motion between 2 objects that are touching. 4. – Newton and Einstein. ASTR 101. Prof. Dave Hanes. Newton . Succeeds!. The orbit of (newly-discovered) Uranus.

Eigenvector (smallest . eigenvalue. ). AT AGE 18 HE ENTERED TRINITY COLLEGE, CAMBRIDGE AS A SIZAR. A SIZAR WAS KIND OF A “WORK-STUDY” ASSISTANTSHIP FOR TALENTED STUDENTS FROM POOR FAMILIES. THEY PAID NO TUITION BUT HAD TO PERFORM MENIAL, SOMETIMES DEMEANING TASKS AND WERE CONSIDERED SUBORDINATE TO TUITION PAYING STUDENTS. WHILE ARISTOTILEAN PHILOSOPY WAS EMPHASIZED THERE HE PREFERRED TO STUDY DESCARTE. HE ALSO IMMERSED HIMSELF IN THE STUDY OF COPERNICUS, GALILEO AND KEPLER Newton’s method. Need initial guess and derivative. Quadratic convergence. Proof via . taylor’s. theorem. x_n+1 = . x_n. – f(. x_n. )/f(. x_n. ). Derivation from point-slope y = m*(x – x_0) + y_0:. ASTR 101.

Famous scientists.. Isaac Newton. Isaac Newton was the first. Man to discover gravity by . a. apple falling of a tree .Sir Isaac . Newton was one of the most . Inspiring scientists of all time.. Isaac Newton was born in England. Isaac Newton (1642-1727). Galileo found that bodies with different masses experienced the same acceleration when dropped to the ground. But he didn’t know why.. Kepler. discovered that the motions of the planets were perfectly reproduced by 3 mathematical relations. Like Galileo, . David Sargent. October 21, 2012. Mars Science Laboratory - MSL.
