PPT-Conservation of Momentum and collisions

Law of Conservation of Momentum With no external force momentum doesnt change Its the opposite of the impulse momentum relationship Ft Δmv Example Consider a gun being fired A gun recoils when it is fired . http://. www.aplusphysics.com. /courses/honors/momentum/. collisions.html. Unit #4 Momentum. Objectives and Learning Targets. Define and calculate the momentum of an object.. Determine the impulse given to an object.. & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . I. . . Collisions. . II. . Work and Energy. Momentum:. an object of mass m, moving with velocity v has a momentum p = m v.. Momentum is an important and useful concept that is used to analyze collisions . Momentum & Collisions. Momentum and Collisions. Momentum is a quantity of motion that depends on both the mass and velocity of the object in question:. Remember. : Momentum is a _______________ quantity, with the same sign as its velocity. As with any vector you can assign any direction as positive and the opposite as negative, but as convention we will refer to . State the principle of conservation of momentum.. Demonstrate the principle of conservation of momentum.. Solve problems about conservation of momentum.. Discuss conservation of momentum in e.g. collisions, spacecraft, aircraft.. Bell Ringer.

We will . demonstrate . and apply the laws of . & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . 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 . AP Physics 1. M. Dimler. What to Expect from this Unit. Momentum. Impulse. Impulse-Momentum Theorem. Conservation of Momentum. Collisions (Elastic, Inelastic, Perfectly Inelastic, and Explosion). Elastic Collisions-Conservation of KE. 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 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.. 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.
