Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields. To support that, he explains that when we place two magnets opposite to each other, the two magnets will repel each other. However he wrote that making force fields and to levitate heavy objects is nearly impossible since we lack advanced technology. For my response, Kaku doesn’t completely explain everything. Suppose that you have a structure on a planet or a spaceship in the middle of nowhere, and suppose you don't want the force field on all the time either because there are times when protection isn't needed.
Module 3: Natural Forces Affecting the Driver Vocabulary: Please define six (6) of the following terms in your own words. Please do not just copy and paste the definition. 1. Gravity - The force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
While studying the planets he realized that they move eternally. Aristotle then came to the conclusion that objects are in between a state of actuality and potentially, while also realizing that change or motion must be caused by something. He joins the four points together along with the theory of matter and then came to the conclusion that there exists something that causes motion and change without itself being moved and that is eternal. He called it the Prime Mover. Christianity was based around Aristotle’s idea of the Prime Mover.
What were the main components of the atmosphere when the Earth formed, and what are the main components today? How and why did they change? The atmosphere of Earth is primarily a mixture of nitrogen and oxygen. Earth’s original atmosphere was probably just hydrogen and helium. They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth.
The earth is also overdue. Every once in a great while, the earths poles shift. The earth’s magnetic field is temporarily disabled as the poles swap out. What makes this so important? When the hotspots on the earth’s surface erupt, they send charged particles at the earth.
Because its density is so high, neutrons spin in the same way that electrons do so must obey the Pauli Exclusion Principle. 6. A pulsar does not pulse, it emits beams of radiation that sweep around the sky as the neutron star rotates, and astronomers detect pulses when they sweep over the Earth. 11. Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays.
The idea could be considered as madness but others may say THIS IS PHYICS!  After the giant nebula has started to converge it forms a Protostar, this Protostar is halfway between a nebula and a star. Eventually it gets to a point where it cant contract any more gas and the tremendous pressure starts to cause tremendous hear, and thus nuclear fusion begins, true story. 
Science Physics Core science questions and answers- Topic 1- The solar system- 1. What is a geocentric model? It is a model with the earth at the centre. 2. Describe two differences between ptolemy’s and Copernicus’s models- What is at the centre of the model and the way in which the planets followed smaller circles in their orbits in ptolemy’s model.
When it does, it will envelope Mercury, Venus and eventually Earth. The only question is what catastrophe will destroy, or render this planet uninhabitable, before that time. In Cormac McCarthy’s The Road, the author gives a view of an earth that has been all but destroyed but gives the reader no specific cause for this broken world. Many ideas and theories have been given. Ranging from gamma ray bursts to nuclear
Gravity By Cindy Grigg | | | 1 Gravity is a force that we experience every moment of every day. Gravity is the basic force in the universe. Every body (planet, moon, star, comet, asteroid, meteor, etc.) in the solar system has a force that pulls things to itself. That's gravity- the force of attraction between all objects in the universe.
