FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature

The Donkey Cart by S.T. Hwang "The best way to find out if you can trust somebody is to trust them." Trust‚ just a five letter word which has a very deep and vast meaning. It teaches people how to care for it‚ for it is very hard to gain and to deal with. Also‚ being trustworthy is one of the most important trait a person must possess for it is the process of being able to place confidence in another person. The narrative tells us about the journey of a man whom his trust was tested

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific

Describing Motion with Words Scalars and Vectors Distance and Displacement Speed Velocity Acceleration Kinematics is the science of describing the motion of objects using words‚ diagrams‚ numbers‚ graphs‚ and equations. The goal of any study of kinematics is to develop sophisticated models which serve in describing (and ultimately‚ explaining) the motion of real-world objects. Much of our lives are spent in motion‚ travelling from one place to another. We measure motion by the rate

Lebanese American University Classical Physics 3 . Projectile Motion Objectives: Students will measure the maximum height H and the range R of a projectile motion. They will study the effect of the shooting angle on H and R. Material used: 4 rulers‚ track‚ metallic ball‚ landing track‚ A4 white paper‚ red carbon paper‚ timer + supply‚ gun + protractor. Theory: A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles: an object

In the late 1960’s and early ’70’s posters of the Black Panther Party’s co-founder‚ Huey P. Newton were taped and plastered on walls of college dorm rooms nation-wide. Wearing a black beret and a leather jacket‚ sitting on a wicker chair‚ a spear in one hand and a rifle in the other‚ the poster portrayed Huey Newton as a symbol of his generation’s anger and courage. He was a symbol of anger and courage in the face of racism and the class in which blacks were placed. His intellect and leadership abilities

PH 110 Lab #7 Applying Kepler’s Second and Third Laws In this lab we examined the elliptical nature of plametary orbits. In the first part we learned the Law of Equal Areas‚ a law concerning the speed at which planets travel; a line connecting a planet to the sun will sweep out equal areas in equal times; "Kepler’s second law means that a planet’s orbital speed changes with its distance from the sun" The procedure that we follow the orbit of Mar for the year 2004 and 2005

four laws of counterinsurgency: The First Law is support of the population is necessary for both the insurgent and counter-insurgent forces. Second Law‚ an active minority can gain support for either insurgent or counter insurgent forces. Third Law‚ popular support is continually conditional. Lastly‚ it takes a true commitment of both effort and resources to win. Of these four laws both President Obama and GEN Petraeus focus on the first and third laws.

Theory: Gravitational acceleration is constant on Earth g=9.8m/s2 Therefore‚ when the golf ball is dropped‚ the acceleration will be equal to gravitational acceleration agb=9.8m/s2 Given there is no air resistance‚ this means that when the golf ball is dropped from a given distance‚ according to the formulas‚ the golf ball will accelerate
