Gravitational constant

highest point of a roller coaster. One by one, the cars start going downhill on the other side, until gravity kicks into action and the full weight of the train is going down into curves, twists, and turns. A roller coaster is a great example of gravitational potential energy changing to kinetic energy. Potential energy can come in many forms. For example, chemical energy can be stored and later converted into heat or electricity.…

Exoplanet Essay 1.0 Introduction An extrasolar planet also known as exoplanet is any planet that orbits a star not within our solar system. The first real discovery of an exoplanet was made in 1995 by the Swiss team of Michel Mayor and Didier Queloz of Geneva. The planet that they discovered was at least half the mass of Jupiter and smaller in size. NASA has confirmed 1746 exoplanets exist and there is surely more to be discovered. The Kepler mission was too find and statistically characterizes…

how long it takes for light to travel. However, we never look on one of the most interesting thing in our universe, stars, and how they function. At first, it may seem simple but as we look more depth into it, it is truly unique. Stars are in a constant fight between…

The similarities of Chapter 14(Kinetics of a Particle : Work and Energy) and Chapter 18 (Planar Kinetics of a Rigid Body : Work and Energy) No. Similarities Examples of chapter 14(Kinetics of a Particle : Work and Energy) Examples of chapter 18(Planar Kinetics of a Rigid Body : Work and Energy) 1 Both energy are scalar quantity The kinetic energy of a rigid body that undergoes planar motion can be referenced to its mass center.It includes a scalar sum of its translational and rotational…

high/low method and secondly one using the unweighted method of least squares. Gradients are found for each of theses lines (along with its error when using the unweighted method of least squares) and these values rearranged to find the value for gravitational…

two-body problem subject to the universal gravitational attraction (Newton’s Law of Universal Gravitation), and then consider special cases of interest for our purpose. 1.4.1. Equation of Motion under Newton’s Law of Gravitation Using the coordinates shown in Figure 1.2, Newton’s Law of Gravitation implies that the two bodies of masses M and m, and the radius vectors r ⃗_M and r ⃗_m , respectively, would exert the following forces of mutual gravitational attraction: Figure 1.2. A…

Discuss in terms of forces and torques how each of these tools can be used to determine the unknown mass of an object. Include in your discussion an explanation as to why mass measurements taken by a spring scale are affected by local variations in gravitational field strength, while those taken by a balance are not. The way a triple beam balance works has to do with the idea that equal masses on each side are being pulled downwards by gravity with equivalent forces. As mentioned before, torque…

structure growth in the Universe as a function of redshift. This map, spanning 3/4 of the lifetime of the Universe will complement the single snapshot at z ≈1100 made by WMAP and Planck. By combining the use of Redshift measurements (4.1), Weak gravitational lensing (4.2) and Baryonic Acoustic Oscillations (4.3), both Dark Energy (DE) and Dark Matter(DM) will be investigated in the following tasks: 1. Construct a three-dimensional Dark Matter map to a depth of z=2. See Figure 2. 2. Measure…

physicists and mathematicians, who was best known for his law of gravitational forces. In 1665, as young Isaac sits under an apple tree, he realized the fall of an apple. He proclaimed that the force pulling the apple onto the ground and the force keeping the moon in orbit around earth are the same. In addition, he came up with the equation: Fg=Gm1m2/r^2, and named this special force, gravity. However, along with his law of gravitational forces, came a question: “If the apple falls does the moon…

multiply the surface area by 16 and get 8,235,496,645 km away. • The sun’s mass is about 2.7 x 107 times greater than the moon’s mass. The sun is about 400 times farther from Earth than the moon. How does the gravitational force exerted on Earth by the sun compare with the gravitational force exerted on Earth by the…
