Two pulses travelling in opposite directions will pass through each other unaffected. While passing, the displacement is simply the sum of the individual displacements. CP 514. SUPERPOSITION OF WAVES. 5. : . Superposition of waves. Chapter . 5. : . Superposition of waves. Superposition principle. applies to . any. linear system. At a given place and time, the net response caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus individually.. . 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 . z. -component angular momentum. The . z. -component of the angular momentum operator depends only on . φ. The . particle-on-a-sphere wave . function is the . eigenfunction. of the . l. z. operator.. In a linear system, the linear responses of linear independent sources can be combined in a linear manner.. This allows us to solve circuits with one independent source at a time and then combine the solutions.. 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. 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. 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. .
