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 . Chapter 7. 7.1 The Impulse-Momentum Theorem. This section deals with time-varying forces affecting the motion of objects. . The effects of these forces will be discussed using the concepts of . i. mpulse and linear momentum.. An object of mass . m. traveling at velocity has a linear . momentum. (or just momentum), , given by . Units have no special name: kg-m/s. With no net force on a particle, its momentum is constant (Newton #1), but any force will change its momentum. . 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 . Have you ever wondered…. How a tae kwon do expert can break a stack of cement blocks?. Why falling on a cement floor hurts more than falling on the grass?. Why a follow through is important in golf, baseball or boxing?. Angular momentum of a rigid rotating object. Conservation of angular momentum. Lecture . 23: . Angular momentum.

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 . mass of an object and it’s velocity. .. . Formula:. p = . mv. mass . (kg). velocity . (m. ⋅. s. -1. ). momentum (kg. ⋅. m. ⋅. s. -1. ). Unit: kg⋅m⋅s. -1. Momentum is influenced by. What is Momentum? Unit 8 Section 3 Momentum Momentum is a property of ALL moving objects Momentum is the product of the mass and velocity of an object. Momentum = mass x velocity ( P=M x V) Momentum is labeled as kg x m/s with a direction. Momentum. Measures how hard it is to stop a moving object.. Momentum can be defined as . "mass in motion.". . All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. .
