Science Notes: Fundamental Forces of Nature All forces in nature may be classified into four types. The gravitational force holds together the universe at large‚ plus the atmosphere‚ water‚ and us to the planet Earth. The electromagnetic force governs atomic level phenomena‚ binding electrons to atoms‚ and atoms to one another to form molecules and compounds. The strong nuclear force holds the nucleus together. The fourth force‚ the weak nuclear force‚ is responsible for certain types of nuclear

yields two integrations: x = x0+v0t+1/2at2 v = v9+at These two expressions show the relationship between position‚ velocity‚ and acceleration at a given time. Newton’s 2nd law states that the acceleration of an object depends on the net force acting upon the object and the mass of the object. If there were no friction in this experiment‚ then the acceleration of the glider would be equal to acceleration of gravity multiplied by the angle between the air track and the horizontal table (g

In “The Use of Force” the doctor and the young girl Mathilda have a very odd relationship. When the doctor first meets the young girl‚ sick and lying on her kitchen floor he founds her to be unusually attractive. When the doctor first meets her‚ him seems to more interested in her looks than what is actually wrong with her. The young girl is trying hard to keep the secret of her sickness and in doing so is very unwilling to help the doctor in anyway. The task the doctor had would have been easier

Physics notes Force is an agent which produces or tends to produce motion in an object‚ stops or tends to stop ‚ motion of an object Newton’s 1st law of motion: If an object is at rest‚ will remain at rest until or unless an external force act on it. If an object is in motion ‚ it continues its motion until or unless an external force act on it Newton’s 1st law of motion is also called first law of inertia. Inertia: The tendency of an object to resist any change in its state of motion

to convince people to do what we want‚ but it’s really all about how we do what we do to persuade someone. There are different methods to persuade someone such as in “The Use of Force” by William Carlos Williams where the characters persuade one another just like someone in modern day society would. In “The Use of Force”‚ the doctor finds Mathilda to be “an unusually attractive little thing and as strong as a heifer in appearance” (Williams 1) but Mathilda gives the doctor a distrustful look.

destructive. Not all conflict is a destructive force in our lives. Conflict is more of a constructive force that results in building something new no matter how bad the outcome of conflict. If conflict were to be a destructive force then society would fail to advance to the world today‚ instead we would live in a world of anarchy. The type of construction that arises from conflict is the reason why the world is the way it is today. Conflict provides a force that constructs people and the way they think

Vectors‚ Forces‚ and Equilibrium 1.1 Purpose The purpose of this experiment is to give you a qualitative and quantitative feel for vectors and forces in equilibrium. 1.2 Introduction An object that is not accelerating falls into one of three categories: • The object is static and is subjected to a number of different forces which cancel each other out. • The object is static and is not being subjected to any forces. (This is unlikely since all objects are subject to the force of gravity

Use of Deadly force Brian Wheeler CJE1600 There is a time for deadly force and there is a time when it is not always necessary. If a suspect just stole something but possesses no threat to anyone physically then no there shouldn’t be deadly force involved. However if a suspect just robbed a bank and is carrying a gun and intending on harming an officer or mere civilian then the use of deadly force needs to be used. Also if an inmate in a prison escaping an officer should try other methods of
