Absolute Potential Energy: Absolute potential energy is the potential energy needed to be applied on an object to displace it to such a distance where gravitational force doesn't work on it.
Mathematically
U=(-GMm)/r
Here
U is absolute potential energy
G is Gravitational constant whose value is 6.673 x 10-11
M is mass of earth whose value is 5.9736 x 1024 m is mass of the mobile object. r is distance between center of earth and object. Gravitational Potential Energy PE = mgh
We can calculate gravitational force in small parts. F=GMm/r2
If we move one object from 0 point to 1 as shown in figure then r1 is the distance from 0 to 1 and r2 is is the distance from point 0 to 2. r = r1 + r2 / 2
∆r=r2-r1, r2 = ∆r + r1 r = r1 + ∆r + r1/2 =2r1 + ∆r /2 = r1 + ∆r /2

The "2nd U.S. Circuit Court of Appeals" held that those business practices that have had a disparate impact effect on the older workers are now considered to be actionable under one national anti-discrimination law (Hamblett, 2004). The case does reaffirm a second Circuit precedent that had been set but which is at odds with what a majority of federal courts have held. The appeals court supported the idea that a layoff plan had been properly brought under the The Age Discrimination in Employment Act of 1967 (ADEA) although the company did not have the intention of discriminating.

The objective of this lab is to find the equilibrium constant of Fe(SCN)2+ through multiple trials using a spectrometer. Since one chemical is colorless and the other is colored a spectrometer can be used to monitor amounts of each in the solution. By completing multiple trials an average can be reached for the value of the equilibrium constant of Fe(SCN)2+.
When the eggs are dropped onto the pillow, the eggs will bounce a little and stay whole.
An elastic collision is one in which total kinetic energy as well as total momentum
The energy of a body or a system with respect to the motion of the body or of the particles in the system

The purpose of this experiment is to find the empirical formula of the compound MgO commonly referred to as Magnesium Oxide. This empirical formula will be a whole number ratio of the two elements located in the compound. You can achieve this formula by taking the moles of Magnesium and the moles of Oxygen and dividing them. This will give you the ratio of the compound MgO and therefore give you the empirical formula.
Theoretically, the empirical formula for magnesium oxide was MgO, only one of each element, and the percent composition of 60% magnesium and 40% oxygen. However, from the data collected during the lab, the empirical formula was found to be Mg2O, and the percent composition was calculated to be 75% magnesium and only 25% oxygen. These results point towards a more magnesium-heavy product being synthesized, with a practical magnesium percent composition rise of 15%.

The purpose of this lab is to see how many blades on a windmill will create the most voltage. Another purpose of this lab is to find out at what blade angle will the windmill create the most voltage. Wind energy has been used for thousands of years because it is a renewable source; therefore, the wind power will never run out. WInd energy had been put into use by 5000 BC ,and simple windmills in China were used for pumping water, and vertical-axis windmills were grinding grain in the Middle East. The new technology of wind energy was taken to the New World in the 19th century for pumping usage and to generate electricity for homes and
b = the amount by which Y changes when X changes by one unit with all other values held the same.
