Years after his death Physicist Isaac Newton (1642-1727) used these laws to help him develop his law of universal gravitation. The law of Universal Gravitation states that: "every particle in the Universe attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them" (Serway 424). This essential means that the force of gravity increases the larger the masses are and decreases the farther away the masses are. The formula to determine the the magnitude of the gravitational force is: Fg = G (M1M2)/R^2 G is the Universal Gravitational Constant, M1 and M2 is the mass of the two objects and R is the distance between them. On Earth the force of gravity causes all objects to accelerate at 9.8m/s^2.
There are many different kinds of energy. Mechanical energy deals with things in motion. Like all energy, it comes in two forms, kinetic (the energy of motion) and potential (the energy of position and/or configuration). Kinetic energy is the energy an object has because of its motion. Potential energy is the energy an object has because of its position.
3. What are the sources of heat inside of Earth? Magma, earth’s internal heat. 4. What is the difference between confining pressure and differential stress?
Chapter 17 Vocabulary AP CHEMISTRY 1. Electromagnetic radiation: radiant energy that exhibits wave-like behavior and travels through space at the speed of light in a vacuum 2. Wavelength: the distance between two consecutive peaks or troughs in a wave 3. Frequency: the number of waves (cycles) per second that pass a given point in space 4. Planck's constant: the constant relating the change in energy for a system to the frequency of the electromagnatic radiation absorbed or emitted, equal to 6.626 X 10^-34 J 5.
Mass/weight/density Mass and weight both work together to make density. The man that found out how to calculate the density was a scientist named Archimedes. The definition of mass is anything that has matter. Weight is the amount of gravitational pull on one thing. In this experiment we tried to figure out if mass, weight and density were related.
Convection is another method of heat transfer. This occurs when heat is transported through a large movement of heated molecules. The temperature of a liquid is relative to its density and this is when convection occurs. Cooler rocks higher in the mantle are denser than the hotter rocks below them and this is where gravity forces the colder rocks down, as they are heavier. Convection dominates the thermal conditions in the areas where large amounts of fluids, mostly being molten rocks, exist, and therefore it controls the transport of heat from the mantle and the fluid outer core.
The magnetic field permeates the tissue and causes the nucleus scale magnets in the tissues to rotate. By observing what frequencies are absorbed by the atoms the doctors can determine what sorts of atoms are present at a particular place in the body. 2. Explain how a sound is actually a form of energy? In what medium do sound waves travel?
Looks like a real solar system. It is use to illustrate the relative positions and motions of the planets and other objects/particles in our solar system. The principal components/parts of it are the large bulb that is use to represent the sun which is the center of our solar system ,those round objects as the nine different planets or bodies in orbit the sun and that are bounded by gravity, its body and the stand that support the large bulb. The four small inner objects are use to represent Mercury, Venus, Earth, Mars that are also called terrestrial planets which are composed of rock and metals. There are also four outer objects which are use to serve as the gas giants.
Q60. The radius of the Earth and the radius of Jupiter are in the approximate ratio 1 : 11. The mass of the Earth and the mass of Jupiter are in the approximate ratio 1 : 320. You will need the following information. The Earth and Jupiter are spherical The volume of a sphere of radius r is (a) Show that the approximate ratio of the volume of the Earth to the volume of Jupiter is 1 : 1331.
As the athlete is spinning the hammer in a circle there is force acting upon it and that mean Newton’s Laws are relevant to the situation. The circular movement of any object depends on the three Newton’s Laws. 1. If a body is at rest, it will remain at rest unless the forces acting upon it become unbalanced. 2.Force is equal to mass times acceleration.
