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 PM x V Momentum is labeled as kg x ms with a direction. 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.. 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.. Physics. Dr. Michael Cooke. Dr. David Schmitz. Fermilab. FUN. Newton’s Laws of Motion. o. Objects in motion want to stay in motion and objects at rest want to stay at rest. Forces. change motion:. 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. rd. Law and Momentum. 12-3 Objectives: On page . 118, . write and Answer the Following:. 1.What is Newton’s 3rd Law?. Before:. After:. 2.What is needed for an object to have a large momentum?. Before:. 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. 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. 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.. 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.. Chapter 4. 4-1 Accelerated Motion. Newton’s Second Law of Motion:. Definition: . A net force acting on an object causes the object to accelerate in the direction of the force.. The magnitude of acceleration is affected by the size of the force and the mass of the object. 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. .
