PPT-Momentum, Work, Power, and Efficiency

NS3310 Dr Hoge Cartoon Laws of Physics Law I Any body suspended in space will remain in space until made aware of its situation Law II Any body in motion will tend to remain in motion until solid matter intervenes suddenly. 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. 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?. 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. s. Compare the inertia of a semi truck and a roller skate… . Will the truck always have more inertia than the roller skate? . Will it always have more momentum than the roller skate?. Warm-Up. Estimate the amount of work the engine performed on a 1200-kg car as it accelerated at 1.2 m/s. Momentum. – tendency of objects to keep going in the same direction with the same speed. Depends on mass and velocity. Has direction. The momentum of a ball depends on its mass and velocity. Ball B has more momentum than ball A. 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. near the ground states of nuclei. = Study by . 16. O(p,pd). 14. N reaction =. Isao Tanihata, H. J. Ong, s. Terashima and E443 collaboration at RCNP. IRCNPC and SPNEE, Beihang University, Beijing, China. 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 . Momentum is a quantity defined as the product of the mass and velocity of an object.. Unit of Momentum. The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.. 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. What is Momentum? Momentum may be defined by its equation: Momentum is a quantity defined as the product of the mass and velocity of an object. Unit of Momentum The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity. 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. . DAIRY PLANT MANAGEMENT (DTT-421). A K JHA. INTRODUCTION. Operation of a dairy plant in a highly effective manner is possible only when all factors involved . are synchronized. . . It is difficult to Perfection .
