PPT-Section 6.3 Apparent Forces

in Circular Motion cont 2015 Pearson Education Inc Centrifugal Force If you are a passenger in a car that turns a corner quickly it is the force of the car door pushing inward toward the center of the curve that causes you to turn the corner. CA Standards. Students know . the atoms and molecules in liquids move in a random pattern relative to one another because the intermolecular forces are too weak to hold the atoms or molecules in a solid form.. This is hard!!!. Lesson Objectives. To relate the apparent magnitude scale to the brightness of stars.. To perform simple calculations relating magnitude differences to brightness ratios.. To distinguish between apparent magnitude and absolute magnitude. Here’s Tim & Mobey on Force. Brainpop. Suppose I asked you to move a heavy desk in the classroom. How would you move it? . hmmmmmmmmmmm...... You might get on one side of the desk and start pushing, Or you might grab the legs and start pulling. . Apparent Weight on a Roller Coaster. WDYS???
