Circular Motion Continues

Honors Physics took time to review and refresh their problem solving skills for rotational equilibrim before moving on to other properties of rotational motion - angular momentum, Newton's 2nd law applied to rotational motion and rotational kinetic energy. The concepts are familiar, they are now simply applied to rotating bodies. For problem solving, here's a hint (especially for conservation of energy problems): ω = v_t/r...

Physics B and F reviewed their torque homework and spent time working with the idea of rotational equilibrium. The problem set for homework will make you think, so here's your hint: Sometimes you need to look at both conditions for equilibrium to be able to solve a problem.

Physical Science completed their simple machines lab. Little problem following directions for the lever piece, but everyone finally pulled together a good set of data. Get the writeups completed (along with your examples of the three classes of levers) for tomorrow so that we can use the information to illustrate our discussion of work and power.
