Objective: SWBAT understand Keplers Laws and their applications.
Warm Up: How far from the earth's
surface must a satellite in space be if it is to feel a gravitational
acceleration that is 1/8th what it would feel if it were still on earth?

Objective: SWBAT review for Monday's test on SHM and oscillations.
Warm Up: Get out your review packet. In the equation x=0.25 cos (8 pi ) t, what do 0.25 and 8 pi represent?

Objective: SWBAT mathematically describe the oscillations of an object in SHM.
Warm Up: A car with a mass of 1300 kg is constructed so that its frame is supported by four springs. Each spring has a force constant of 20000 N/m. If two people riding in the car have a combined mass of 160 kg, find the frequency of vibration of the car after it is driven over a pothole in the road. How long does it take the car to complete two vibrations?

Objective: SWBAT calculate the period of a simple harmonic oscillator.
Warm Up: A block of mass m if allowed to hang from a spring in static equilibrium. It stretches the spring a distance L. The block and spring are then set into oscillation. Is the period of this system less than, equal to or greater than the period of a simple pendulum having a length L and a bob mass m?

Objective: SWBAT calculate static equilibrium problems.
Warm Up: Turn in your outline for Ch 12 and pick up one syllabus for the chapter.
What are the two necessary conditions for static equilibrium? How is this different than the conditions necessary for rotational equilibrium?
