PPT-CE 394K.2 Mass, Momentum, Energy

Begin with the Reynolds Transport Theorem Momentum Manning and Darcy eqns Energy conduction convection radiation Energy Balance of the Earth Atmospheric water Reading Applied Hydrology Sections . . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . Linear Momentum. Momentum is a measure of how hard it is to stop or turn a moving object.. p. = m. v. (single particle). P . = . Σ. p. i . (system of particles). Problem:. How fast must an electron move to have the same momentum as a proton moving at 300 m/s?. Mass energy equivalence. In quantum mechanics , we considered that kinetic energy could be increased only increasing by its velocity. But now dealing with relativistic mechanics we take mass variation into account. (d)define . linear momentum as the product of mass and velocity. (e) define force as rate of change of momentum. (f) recall and solve problems using the relationship F = ma, appreciating. that acceleration and force are always in the same direction. . In classical mechanics, the momentum of a particle is defined as a product of its mass and its velocity, . . In an isolated system of particles, with no net force acting on the system, the total momentum of the system remains the same. However , we can see from a simple though experiment that the quantity . and Momentum Revision Mock 2015. Stopping distances. . . Thinking distance is the distance a car travels before the brakes are applied.. Braking distance is the distance a car travels whilst the brakes are being applied.. You’re Quite Impulsive. A Review of What We Know About Motion. Chapters 2 & 3 introduced us to vectors such as displacement, velocity, and . acceleraton. No mass was included. Chapter 4 introduced forces and mass into the mix. AP Physics. Work-Energy Theorem for Rotation.  .  .  .  . End Slide.  .  .  . Work-Energy Theorem for Rotation.  .  . End Slide.  .  .  .  .  .  .  .  .  . Work-Energy Theorem for Rotation. Electric and . Magnetic fields. What does “mass” mean?. QUIZ at 1:20. 4-dimensional physics. The principle of relativity requires that . if the laws of physics are to be the same in every inertial reference frame, the quantities on both sides of an = sign must undergo the same Lorentz transformation so they stay equal. . Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. By Jonathan. Recap:. Last week we talked about countersteering. What was . countersteering. ?. Turn in the other direction in order to complete a turn.. A while back we mentioned velocity. What was . by Zack Ridgway and Jeffrey Wan . Kinetic energy. Kinetic energy- energy of an object that it possesses due to its motion. . Common examples. A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity..
