PPT-Chapter 6 – Linear Momentum and Collision

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 WarmUp Estimate the amount of work the engine performed on a 1200kg car as it accelerated at 12 ms. You should be able to solve 1D and 2D Momentum problems.. Linear Momentum. Antoine Lavoisier proved that mass was conserved by burning iron in a closed system. (The mass of any closed system remains constant.). Watch. : . https. ://www.youtube.com/watch?v=. OiTiKOy59o4. What. . happenend. . with. Sandra Bullock?. What. is the action force?. What. is the . reaction. force?. Do the action force . and. the . 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?. Momentum and Impulse. Lecture PowerPoint.

How can we describe the change in velocities of colliding football players, or balls colliding with bats?. Momentum is Conserved. So . far, . we . have only . considered the momentum . of . one object at a time.. Now we will look at two . (or more) . objects interacting with each other. .. Picture this. . . . (Linear) Momentum, p. ● . is mass times velocity. . . vector. !. . ● . . (p) = kg m/s. ► . a 1 kg object moving at 1000 m/s has the same momentum as a 1000 kg object moving at 1 m/s (p = 1000 kg m/s). Notes. Momentum Conservation Principle. One of the most powerful laws in physics is the law of momentum conservation. . For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects . 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. ?.

Conservation of . linear momentum. Collisions. Momentum. , p. The linear momentum . p. of an object is the product of the object’s mass . What factors affected how fast objects move after a collision? (Think of your lab). Section 1: Momentum and . Impulse. Linear Momentum:. Momentum is defined as . mass times velocity. .. Momentum is represented by the symbol p, and is a . Momentum and Impulse. Objectives:. 1. Compare the momentum of different moving objects.. 2. Compare the momentum of the same object moving with different velocities.. 3. Identify some examples of change in the momentum of an object.. rd. Law. Chapter . 6: Momentum. Momentum = “inertia in motion”. Specifically, momentum = mass x velocity. = . m v . . Eg. Just as a truck and a roller skate have different inertia, when they are moving, they (generally) have different momenta. .
