### Transcript

• 1. Newton’s Law ofGravitation { Astronomy: Lesson 1 By: Chelsea Shi
• 2.  Newtons law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them  aka. Everything attracts to each other in equal force.Newton’s Law of Universal Gravitation
• 3. Formula
• 4. Breaking it up { The variables of the formula
• 5.  Force of attraction  NewtonsF
• 6. G
• 7.  Mass of the first object  Kilogramsm1
• 8.  Mass of the second object  Kilogramsm2
• 9.  Distance between the two objects  metersr
• 10. Written Out Formula
• 11.  Make sure to covert into corresponding unit  The gravitational constant is equivalent to  G/1… fraction so it would go on top to solve  …plug into calculator correct …  Keep track of your time  Do the questions as quick as possible while still getting them correct  You’ll do great Tips
• 12. Practice { Equations
