Welcome back from our mini hurrication.  That storm was spooky!

Objective:  SWBAT understand how work, power and energy are related.

Warm Up:  Pick up an inclass review packet.  Do problem #1.

10/25

Objective:  SWBAT use the pHet site simulations to understand Conservation of energy.

Warm Up:  Get out your netbook, log onto Edmodo.  Open the file for Energy Park 1 and the Energy Park Sim.  Get to work!

10/24

Objective:  SWBAT calculate work and power.

Warm Up:  List the key equations for work, power and energy.  Then determine the potential energy of a 5 kg box at the top of a 5 m high ramp that is at an angle of 30 degrees above the horizontal.  If the ramp is frictionless, what is the speed of the box when it has slide half way down the ramp?

10/23

Objective:  SWBAT determine the work and power needed to walk vs. run up a flight of stairs.

Warm Up:  Pick up a worksheet and turn in your chapter outline.  Define the terms work, power and energy.

10/18

Objective:  SWBAT review for your test on Uniform Circular Motion.

Warm UP:  Get our your Forces Review Packet and your Forces In Class Examples Packet.  Which of Keplers Laws states that a planet's speed will be faster when it is closer to the sun when compared to the same planet that is further from the sun at a different point in its eliptical path?

10/16

Objective:  SWBAT calculate centripetal force.

Warm Up:  A model airplane has a mass of 0.90 kg and moves at a contant speed in a circle that is parallel to the ground.  Find the tension in the guildeline (length 1.7 m) for speeds of 19 m/s and 38 m/s.

10/4

Objective:  SWBAT calculate Newton's 2nd Law problems with friction.

Warm Up:  Get out your In Class Examples packet and complete #9.

10/1

Objective:  SWBAT calculate the force of friction on an object.

Warm Up:  Pick up three pages and staple.  Do Question 1a.
