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

There is limited number of supplier because most of the companies like Research in Motion are designing‚ manufacturing and programming all the devices themselves. However there are numerous hardware and software suppliers. Competitors have a high power. There are many equally balanced competitors. Moreover‚ there is a limited differentiation

Force‚ Motion‚ Newton’s Laws‚ Momentum‚ and Impulse What is force? Force is a push or pull upon an object resulting from the object’s interaction with another object. There are two types of force‚ contact forces‚ and forces resulting from action-at-a-distance. A contact force can be frictional forces‚ normal forces‚ applied forces‚ and air resistant forces. The formula for contact force is F = ma. This type of force occurs when two objects are contacting each other physically. If you kick a ball

Motion sickness Overview: The motion sickness is a deeper malaise - whose symptoms are nausea‚ vomiting‚ fatigue - due to non-uniform motion caused from traveling in a car‚ a ship‚ a train or a plane. Causes: You get motion sickness when one piece of your offset detecting framework (your internal ear camera.gif‚ eyes‚ and tactile nerves) detects that your body is moving‚ yet alternate parts don’t. Case in point‚ in the event that you are in the lodge of a moving ship‚ your internal ear may sense

One World: Motion Topic: Write an article that explores how the Physics of Motion is (or can be) used to solve a specific problem in a local or global context. Millions of people everywhere around the world make use of the principles of motion to travel up and down quickly within a tall building. The use of elevators has been around since ancient medieval times since then has grown from being powered by a hoist and winder to electric and hydraulic motors1. An elevator
