Gravitational constant

The larger the spring constant – that is, the firmer the spring – the larger the restoring force the spring exerts for a given distortion. The negative sign indicates that a restoring force always points in the direction opposite the distortion. Some springs are soft and have small spring constant (springs in the toaster), others – firm and have large spring constants (automobile chassis). When you step on a bathroom scale, you depress…

Sir Isaac Newton was a mathematician, astronomer, and physicist. He was born on January 4, 1643 in Woolsthorpe, England. His father was a farmer. Newton spent his early years waiting tables, and cleaning up the bedrooms of wealthier kids. After his father died, his mom married a minister and left Isaac to live with his grandmother. When her second husband died she went back to live with Isaac along with her other children. Isaac went to King’s School in Grantham, England. Here he met an…

average Nusselt number is used for heat transfer analysis in natural convection expressed as where and are the constants depending on the geometry of the surface and flow regime. For value of for laminar flow and turbulent flow are usually equal to and , respectively (Cengel, Y.A. 2007). 3.2 Basic Heat Transfer Heat is normally absorbed or rejected by a working substance at a constant pressure. The heat transferred without a phase change results in a change of temperature is called…

situation, they may lack the strength to preform at 100%. (http://www.nsbri.org/DISCOVERIES-FOR-SPACE-and-EARTH/The-Body-in-Space/). When thinking about the long-term trip to Mars, this becomes especially risky since astronauts are without the 1g of gravitational strength the earth provides for over two years. To counter this problem astronauts undergo intensive strength training exercises two to two and a half hours a day along with an adequate diet…

The four fundamental forces have been around before mankind. These forces shape the way we live and interact with the objects around us on a daily basis. These forces are so important, they are in existence throughout the entire universe. Black holes, the formation of planets, galaxies and stars are all because of gravity and these same celestial bodies have their own electromagnetic forces and the strong and weak nuclear forces are. Since everything in the universe is made of atoms, there is…

the forces between matter particles are all supposed to be carried by other particles. Then, the particle emits another force, changing the velocity of the matter particle, in a cannonball way. The net result of the emission and absorption remains constant” A particle exchange also happens, Hawking states, and forces "arise from the exchange of force-carrying particles" With his further discovery and involvement with the quantum theory, Hawking…

for home or rootedness. In fact, I decided to move to Canada and pursue a better future. In my country, Venezuela, our perspective of life and success is completely different from that of Chinese. I always seek self-improvement; which implies the constant search for the dream job with adequate…

tumbling, and jumps. Cheerleading is a sport that involves all these tasks and much more. Cheerleading consists of many concepts of physics, such as Gravity, Newton Laws of Motion, momentum, torque, potential and kinetic energy, velocity, force, gravitational acceleration, free fall. I will explain the definitions of each concept, so readers will be able to get real meaning as to why these concepts consist of cheer leading. Gravity is the force that attracts a body toward the center of the…

goal is to examine the correlation between position, velocity, time, and acceleration of objects, moving in one or two dimensions. Each and every experiment will be conducted under different conditions. For example, the first experiment requires a constant force (gravity) to act on the object, the picket fence. This experiments other condition is that we neglect friction. This object should be in nearly ideally circumstances. In the second experiment, the conditions are slightly different… In…

the slope of the wooden plank, the faster the car will go therefore the increase of the severity of the crash. Variables: Independent Variable – The height of the ramp Dependent Variable – Distance that the dummy flies – the velocity of the car Constant Variables: - Size of the car - Angle of the wooden plank - Same equipment - Same direction the car is going every time - Length of the timber needs to be the same - Stopper needs to be the same - Weight of the dummy - Weight of the car - Same…
