Friday!

A few classes were low on students due to the band/chorus hoohah, but we made do nonetheless. Physics discussed yesterday's lab and used it to introduce the concept of collisions. Remember that both perfectly inelastic and elastic collisions demonstrate conservation of momentum and the same problem-solving skills apply. Only elastic collisions demonstrate kinetic energy conservation; however, inelastic collisions demonstrate a loss of kinetic energy. Physical Science students spent the period working on problems dealing with buoyancy and pressure. I posted the solutions on the course webpage for your two worksheet sets. Honors Physics discussed tangential velocity/acceleration and their connections to their angular counterparts. Centripetal acceleration was introduced and Monday's lab will allow you to investigate centripetal force and the resulting effects on motion. Have a good weekend!
