Read the Physics Talk on pages 177-178 and answer the Checking Up questions (1-3).

Answers to the Physics to Go questions:
1) Since an object in motion tends to stay in motion, the ball will keep rolling at a constant speed for as long as the surface remains horizontal.
2) The ball will reach a vertical height of 20 cm before it begins to roll down again.
3) It does not seem possible to eliminate friction to arrive at perpetual motion in the real world, except perhaps in deep space far away from the influence of any source of gravity (aka any object with mass).
4) Because the ice exerts almost no frictional force on the hockey puck, the puck will continue to slide with almost constant speed in a straight line until a force is exerted upon it. If the object it hits exerts a force in the direction opposite its motion, the puck will slow down, stop, or even change direction depending upon the nature of the force. If the force is in another direction, the puck's direction and possibly its speed will change due to the force.
For tonight:
1) For question #1, give a short explanation why each choice IS an example of inertia
2) Complete the rest of the worksheet following the original directions.

Wednesday, February 10
All of the following work should be done on loose-leaf (or typed and printed):
1) Complete the "What Do You Think Now" questions on page 141
2) Complete the "Essential Questions" on page 142
Also, be prepared to give your 'inertia demo' on Friday!
Finally, watch this great video and see balanced forces at work!

Tuesday, April 9
Read the rest of the Physics Talk and answer the 'Checking Up' Questions. (*Note: you do not need to outline the second half, just read it and answer the questions)
Also, start thinking about your inertia demo for Friday!
