marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity is small‚ the direction of ∆v is nearly radial (i.e. directed along the radius). As ∆t approaches 0‚ ∆v becomes exactly radial‚ or centripetal.

Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist‚ and the first Greek philosopher

Janay Wright-Parks Physics-Sports Paper Brad Ingram 29 March 2013 Physics of Gymnastics In the world of sports‚ physic concepts are being applied every day. Most people who play or watch a sport don’t think about the physics behind it all. When I watch a sport like gymnastics‚ I am always amazed at how a person’s body can bend and twist in the way that gymnasts bodies do. It is nothing but physics. Angular momentum is the main physics concept used in gymnastics‚ and this can be seen in events

to fall‚ the potential energy turns into kinetic energy giving the yoyo linear momentum and angular momentum. Since the yoyo is falling straight towards the ground‚ this is called the linear momentum. The linear momentum can be calculated using a simple formula p=mv Momentum = mass * velocity. As the spring unwinds‚ the spool spins which creates angular momentum. Definition of angular momentum is “a quantity associated with how an object moves around a

Big screen or small screen? Motion pictures captured the hearts of audiences from their birth and have won millions of devoted fans around the world. Even though later technological developments‚ such as the television‚ the video and more recently the DVD‚ made private viewing of motion pictures possible‚ the big screen has not lost its appeal. Based on my experiences‚ I prefer going to the cinema. There are several reasons for the movie theaters’ permanent popularity. First‚ even the most sophisticated

OThe Physics of Airplanes Background: At any given moment‚ roughly 5‚000 airplanes crisscross the skies above the United States alone‚ amounting to an estimated 64 million commercial and private takeoffs every year (source: NATCA). Considering the rest of the world ’s flight activity‚ the grand total is almost incalculable. In order to understand how airplanes fly‚ we must break down the parts of an airplane and understand the physics behind the airplanes most important components: the engine/propeller
