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.
For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. 2. Inertia - A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. 3. Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration.
Chapter 14 1. Radio galaxies have sources of unusually strong radio waves emitted on either side of the galaxy and active galaxies are spirals with small, highly luminous cores like Seyfert galaxies, they also have nuclei that are produced by matter plunging into super-massive black holes. 6. By observing the velocity of the stars that orbit the black hole or by the rotational speed of its accretion disk. 10.
Catapults were an absolute revelation in weaponry. Although they are very hard to create, they use very simple forms of physics to complete their task of destruction. The catapult has a basket on the end of a movable arm strong enough to hold the weight of the object it is intended to hurl. Tension is applied to the arm, which is forced down and then locked in place. People in ancient times used twisted ropes to create tension.
Lab: 3/28/2014 Acceleration of the air hockey punk Background information Pulley system is a device that is made of grooved wheels. It is a popular tool that uses to help people to lift up heavy objects with a simple structure; rope and a wheel. The design of the pulley is base on Newton's second law( if the net force is not balance ,the object accelerates in the direction of the net force). The pulley system that was used in this experiment. The weight was tightened at the end of a rope, during it is dropping toward the grand, there is a acceleration due to gravity; as a result net force of the punk was not zero( equal the force of gravity), it accelerated and moved toward
Activity 4: If you put a pile of tin plates on the top of the generator’s globe, they will fly off one at a time. Since each of them will be picking up some of the excess charges the plates repel each other and they will fly off one at a time. Activity 5: A piece of tinsel or Christmas tree icicles will first be attracted to the globe by induction, just like when you stick a charged balloon to the wall, and then repel away from the generator after it picks up some excess charge. Activity 6: If you start with your hands on the globe and then turn the generator on you won’t get a shock, because the charge doesn’t get a chance to build up. The charge will continually leak into you and then through you to the ground.
The one problem with that is, how. The problem with this is that the cockpit is frictionless and it cannot follow the engines because it's connected to a cable. If you go straight and turn right, the cockpit will still move forward until the cable reaches the maximum length and pulls it at the direction the engines are going. A perfect example would be attaching a rope about 6 ft to a wagon and start running straight with it. As you run straight, the wagon will follow.
2014. Retrieved from: http://www.britannica.com B. Compare and contrast electric force and magnetic force. B) With Electric force movement is the key, unlike magnetic force where it exists with stationary charges. With Magnetic force no movement is necessary in contrast to electric force.
These protons and neutrons of the nucleus are called nucleons. The force that holds these nucleons together inside the nucleus is called the strong nuclear force. This force has special properties as it is independent of charge and is stronger than the electrostatic repulsion forces between protons. This understanding of stability has allowed scientists to
Abduction - A form of nondeductive inference, also known as inference to the best explanation. The Surprise Principle and the Only Game in Town Fallacy are relevant to deciding how strong an abductive inference is. Analogy argument – a nondeductive inference in which one infers that a target object T has some characteristic on the ground that T is similar to some other object A the analog), and A is known to possess that characteristic. (e.g. Other galaxies probably contain life, since they are quite similar to our own galaxy and our own galaxy contains life.)
