Gravitational constant

Introduction This practical was an investigation involving the use of a tennis ball and a meter ruler. The tennis ball was held and dropped at a specific height above the ground. The height of the bounce was then measured. This investigation was carried out to find out whether the efficiency of the bounce varied with the height of release of the tennis ball. If the bounce were 100% efficient, then the tennis ball would have bounce off the ground and return to the starting height. Research…

dust. In many cases, the ingredients for stars laid dormant for millions, perhaps billions of years until an event disturbed them ("Star birth", 2013). As Isaac Newton states in his first law of motion, “An object will stay at rest or travel at a constant velocity until acted on by a force,” and the same remains true even at the massive scales of the Universe. These clouds of gas and dust can be billions of miles across (Chinn, 2010b), and as such, require significant events to occur to…

Fluid dynamics and Bernoulli's equation Moving fluids Fluid dynamics is the study of how fluids behave when they're in motion. This can get very complicated, so we'll focus on one simple case, but we should briefly mention the different categories of fluid flow. Fluids can flow steadily, or be turbulent. In steady flow, the fluid passing a given point maintains a steady velocity. For turbulent flow, the speed and or the direction of the flow varies. In steady flow, the motion can be represented…

to be constant although the flow rate increase. This is slightly equal with the fluidization theoretically idea where the pressure drop should be constant after the minimum fluidization since the solid particles are suspended in the flow up of the gas stream. The drag force was equal to the gravitational force since the weight of aluminum oxide is buoyed by air. Starting from Q = 12.0 to 20.0 L/min, the pressure start to increase which mean the drag force was not equal to the gravitational force…

distributions of matter and energy throughout the universe. All objects have gravitational pulls but as an object becomes more massive, its gravitational pull increases and takes precedence over the gravitational pulls of other smaller objects as demonstrated by the solar system in which Earth resides. Earth’s moon rotates around Earth due to Earth’s gravitational pull while Earth rotates around the sun due to the sun’s gravitational pull. Note how the less massive bodies orbit the more massive…

(3.8) where is the product of the gravitational constant and mass of Triton, and refer to the radius vectors of Triton and Nereid respectively and . In spite of the fact that Nereid is classified as a distant satellite, the evolution of its orbit is presented as regular enough with practically secular variations of pericentric argument and node longitude, and with a conditionally periodic change of eccentricity and ecliptic inclinations.…

Our universe was created 13.7 billion years ago. The Big Bang theory proposes that this creation resulted from the rapid expansion of matter with infinitely large density and high temperature, which marked the true origin of the universe. Physicists decided to introduce a new phenomenon called time, and agreed that “time” was born once the Big Bang banged. Simply defined, time is the measure of durations of events and the intervals between them. In non-relativistic physics, physicists consider…

During my experiment, the same human figure is used. As a result, the weight which is one of the external forces acting on the ski jumper remains constant. Moreover, the velocity of a figure is controlled constantly as 2.5m/s. In addition, the drag coefficient, the area and the density of the air have the same values. These mean it is available to control two main external forces acting on the ski…

of conservation of energy in PHYS221 with Micheal Greiner. We learned that energy is always conserved and the initial energy of the system should be the same as the final energy of the system. In other words the total energy of an isolated system constant if it is non dissipative meaning there are no energy loss. We did not relate this conservation of energy law with waves, but we did a lot of examples like a cart going down a ramp. The…

Seaghan Kinneen 8.5 billion miles from the Sun, over ninety-one times the distance between the Earth and the Sun, stands the newest addition to the Solar System. 2014 UZ224, located some 4.83 billion miles beyond Pluto, joined Ceres, Eris, Haumea, Makemake, and the aforementioned Pluto, as the most recently discovered Solar System Dwarf Planet. To understand the definition of a Dwarf Planet, one must understand the definition of a regular planet. In a 2006 assembly that has gained notoriety…
