PPT-Conservation of Momentum - Outcomes

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 eg collisions spacecraft aircraft. If a system has . no external forces . acting on it (. eg. no friction), then the system is . isolated.. Total momentum in an isolated system is said to be . conserved. . . A . system. is a pair or group of objects that are interacting in some way.. http://www.aplusphysics.com/courses/honors/momentum/conservation.html. Unit #4 Momentum. Objectives and Learning Targets. Define and calculate the momentum of an object.. Determine the impulse given to an object.. 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 . Physics. Problem #1. A 1500 kg car traveling +6 m/s collides with a 2000 kg truck at rest. The vehicles collide, but do not stick together. The car has a velocity of -3 m/s after the collision. What is the velocity of the truck after the collision? . & 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:. . Excerpts . from . Chapters 9 and 11. Impulse and Momentum. Newton’s . 2nd. Law of motion can be rewritten by using the definition of . acceleration. as the change in . velocity. over the change in time.. @. robeastaway. Maths of everyday things. Leonard Euler. (picture here?). Odd socks. Lampard’s disallowed goal. World Cup 2010. England v. Germany. it’s the spin that kept it out. Bouncing balls. 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). & 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:. . Law of Conservation of Momentum. With no external force, momentum doesn’t change. It’s the opposite of the impulse momentum relationship!. Ft = Δmv. Example. Consider a gun being fired.. A gun recoils when it is fired. . 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? 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. .
