Unformatted text preview: Chapter Six: Momentum and Collisions I) Linear momentum (p): p = mv A) Vector quantity B) Can be broken down into its components C) More momentum an object has the more force that has to be applied to stop it in a given time II) The net force acting on an object is equal to the change in momentum divided by the change in time (p/t = F net ) III) Impulse: continuous application of a force over a period of time A) I = Ft = p = mv f - mv i B) Vector quantity with same direction as the constant force acting on the object C) Measured in kilogram meter per second (kg-m/s) D) Impulse-momentum theorem: impulse of the force acting on an object equals the change in momentum of that object E) Magnitude of the impulse delivered by a force during the time interval t is equal to the area under the force vs. time graph or equal to F av t (p = F...
