Study Guide for Exam 3 Momentum (and impulse) -know how to calculate the momentum of an object -definition of the impulse provided by a force -how it is related to the change in momentum of the thing that the force is applied to -impulse and momentum are vector quantities -impulsecan easily be expressed in terms of the average force over a time interval -collision change in momentum of one or more objects -can relate (through the impulse) to the average force. You should know what it means to say that the total momentum of an isolated system is conserved. -“isolated” means that there is no net external force -recognize what systems this applies to -know how to use this principle to solve problems involving collisions or other interactions between parts of a system -vector quantity may need to work with x and y components. - did not cover angular momentum (section 9.7 in the textbook) energy and work (the transfer of energy ) -know how to calculate the work done by a force on an object -when the force and displacement vectors are parallel, antiparallel, or at some other angle. -work can be positive, zero, or negative
