Monday, November 17, 2008 - Blocks 1 and 3

Stamped homework, RA 4.4.
Went around room asking what students learned from Friday's class. Wrote answers on board.
Went over worksheet as a review of Friday's demos.
Collected RA 4.4 and any CD 6.

Showed clips from Independence Day video. Physics is everywhere...except Hollywood. Hollywood does not understand Newton's 3rd Law. Showed results of calculations for reaction force.

Suppose you have a jar of flies on an electronic balance and all the flies are sitting on the bottom. How would the scale reading change if the files took off and few around the jar. Referred to finger in water demo - the scale reading would not change.

Demo with flying saucer on force plate - same reading when it is resting on plate as when it is hovering above it.

Students did Horse Sense worksheet in class. Voted on best pictures.

Handed out RA 4.5 for homework due tomorrow.
