Today we had notes and demonstrations regarding:
Mass vs. weight
Balances vs. Scales
Adding Forces
Newton's first law: Inertia
Newton's 2nd law: Acceleration depends on mass of object and net force applied... Fnet = m*a
Tonight's homework: Read p. 102-109; Work problems on p. 111: #2,3,5-7
An announcement: CERT members - the training has moved from Friday to tomorrow at 8:30.
Seniors: Fun labs: model airplane lab practical - for practice, not for points, and playing with the air track to prepare for tomorrow - attempting to show Newton's 2nd law experimentally.
