Homeostasis is defined as “the maintenance of a constant internal environment‚ within narrow limits‚ despite changes in the external environment.” It is why animals are able to survive in such a vast range of environments. For their bodily cells are able to sustain their function despite change‚ thus‚ enabling the animal to increase the survival of their species. Homeostasis is done through a specific set of receptors‚ effectors and an overall control system‚ which ensures the body sustains healthy

calculating momentum and kinetic energy. We are interested in how physics can be calculated with Calculus which will allow us to calculate a number that is much closer to reality then simple answer from algebra. We first thought about this topic because we know that kinetic energy is probably related to momentum. The formula of kinetic energy is [pic] And the formula of Momentum is [pic]. When we look at the two formula‚ both of them involves mass and velocity. By integrating the momentum formula‚

proper game would never commence. Not only are tennis serves important‚ they also should be executed correctly to achieve the best possible outcome. I will evaluate my serve in regards to three major biomechanical principals‚ force & motion‚ momentum & inertia and projectile motion. (Hustler‚ 2012) Force is the change in the velocity of an object. Force changes when the objects motion changes usually by the pushing and pulling of the motion on that object. Force incorporates the law of acceleration

whyyyyyyyyyyyyyyy.initial momentum = final momentum assume a linear collision‚ since no angles are given 0.05kg*0.6am/S + 0 = 0.05kg*-0.2am/S + 0.03kg*v v = 1.3 am/S It should be noted that this data isn’t valid -- the larger mass marble will continue to have "positive" velocity after colliding with a smaller mass marble. Think Newton’S cradle. I suspect that the overall KEN has increased in this problem‚ a no-no (but I haven’t calculated it). initial momentum = final momentum assume a linear

sample The second law states that the net force on an object is equal to the rate of change (that is‚ the derivative) of its linear momentum p in an inertial reference frame: [pic] The second law can also be stated in terms of an object’s acceleration. Since the law is valid only for constant-mass systems‚[16][17][18] the mass can be taken outside the differentiation operator by the constant factor rule in differentiation. Thus‚ [pic] where F is the net force applied

corresponding antiparticle are annihilated (for example‚ electron-positron annihilation). In empty space‚ the photon moves at c (the speed of light) and its energy and momentum are related by E = pc‚ where p is the magnitude of the momentum vector p. This derives from the following relativistic relation‚ with m = 0:[15] The energy and momentum of a photon depend only on its frequency (ν) or inversely‚ its wavelength (λ): where k is the wave vector (where the wave number k = |k| = 2π/λ)‚ ω = 2πν is the

yoyo is allowed 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

but lost the Battle of Gettysburg. Therefor the North has now won and has stopped the South’s winning streak. Gettysburg was a turning point in the Civil War because the North is gaining momentum while the South is losing momentum. Gettysburg was the turning point because the North has started to gain momentum and was having this cause to fight for. At this time a lot of soldiers from both sides have died. President Lincoln had come and gave the Gettysburg address. In document D Gettysburg address
