Test 4 Study Guide Chapter 7 – Internal Energy o Specific heat capacity: o Energy transfer due to temperature differences: o Energy dissipation and air resistance: Chapter 9 – Multiparticle Systems o Center of mass o The momentum of the center of mass can be derived from the above equation by multiplying both sides by the total mass and differentiating position to velocity: o Multiparticle Kinetic Energy: o Translational Kinetic Energy: o Vibrational Energy: o Period and Angular Speed: o Moment of Inertia: o Sphere: o Disk/Cylinder: o Rod: o Rotational Kinetic Energy: o The point particle system emulates motion of the center of mass. It takes the real system and compresses it to a single point, but contains forces of equal magnitude and direction. o The point particle system has no rotational motion, no vibrational motion, and no internal energy – the only energy measured is translational kinetic energy.

Unformatted text preview: Chapter 10 – Collisions o A collision is elastic if there is no change in internal energy of the interacting objects, so o In an inelastic collision, the internal energy of the objects in the system changes, so , however total momentum does not change because momentum must be conserved o If the collision is elastic, cart 2 moves with the speed cart 1 used to have, and cart one comes to a stop o If the collision is inelastic, the carts stick together and move with half the original speed o If the system is chosen as everything, therefore leaving nothing as the surroundings, then . o During a collision, the momentum of a system stays constant and it can therefore be concluded that . o When solving for internal energy, keep in mind ....
