- Choose one of the Newton's laws and explain it. What is the importance of this law? Give an example in your daily life about this law.Sir Isaac Newton's important book Mathematical Principles of Natural Philosophy was one of the most influential works in the history of science. What physical laws did Newton assert in its pages? What is Newton's Law of Universal Gravitation? How did Newton develop his understanding of how objects in space move to reach the conclusions stated in his book, Mathematical Principles of Natural Philosophy?What is the concept of the second newton's law? and can you give an example.
- Distinction between Newton's 1st Law of Motion and Galileo's Assertion A. Do this: Roll the ball downward, upward and on a level plane. When the ball rolls down the plane, what happen to its speed?Why? A When the ball rolls up the plane, what happen to its speed?Why? When the ball roll is rolling on a level plane, will its speed change? D.Is there a difference between Galileo's assertion and Newton's first law of motion? 44 B.2. Write down the equation for Newton's Law of Universal Gravitation. Sketch a graph of the force of gravity over great distances. Mark two separate distances, d¡ and d,.

- Why is Newton's version of Kepler's third law so useful to astronomers? It is the only way to determine the masses of many distant objects. O It tells us how rapidly a planet spins on its axis. O It explains why objects spin faster when they shrink in size. O It tells us that more-distant planets orbit the Sun more rapidly.5. Calculate the weight of a 155 lb. person on Earth. (Calculate your own weight just for fun [do not write it down] so the next time someone asks for your weight you can give them the correct answer in Newtons!) 1) ude of the If you were to jump on a bathroom scale, explain how the scale reading would change before it settles to read your actual weight. Use Newton's Second Law to justify why this happens. O ADICAIL Rights Resenied (2019)Kepler's Third Law and Newton's Law of Universal Gravitation (a) Use Newton's Universal Law of Gravitation and what you know about centripetal acceleration/force to derive Kepler's Third Law for a planet in a circular orbit about the sun: T² = Kr³ K = constant = 4²/GM where T is the orbital period of the planet (the time for one complete orbit), r is the radius of the planet's orbit, M is the mass of the sun, and G is the universal gravitational constant. (b) Determine the metric system units of K and show that they make the units of T² – Kr³ work out correctly. (c) The earth orbits the sun once per year (365 days) and its average orbital radius is 1.50 x 10¹¹ m. Use this information and Kepler's Third Law to estimate the mass of the sun in kilograms. [answer: about 2 x 10³⁰ kg] (d) The radius of the sun is about 7 x 108 m. Use this radius and the mass of the sun estimated in part (c) to estimate the acceleration of an object near the surface of the sun. [answer: about 300 m/s²] F₂ =G…
