This has to be one of the easiest packets you will get. You will need to go to pg. 208 and read through that chapter and get all the formulas in it. Be sure to read every problem carefully and realize the direction the object is moving in. That will determine if the number is positive or negative. If the problem says "decrease in kinetic energy" then they already know it is going to be a negative number so do not punch in a (-) sign!! Also remember that your initial momentum is always the same as your final momentum. The only thing that changes is the velocity which is usually what you are looking for. And watch your units! Be sure you are punching the right numbers in too. That is why I missed some of mine!

The first thing you need to do when you start this chapter is check out all the formulas. The unit of force newton is kg*m squared over s squared. It helps to change all measurements to Kg and when it as for velocity you can use negative or positive to show direction and when it asks for speed you just give the absolute value. When measuring newton you use the absolute value also.

The most helpful thing is to read and write ALL bold boxed formulas down before beginning your work! Make sure you take notice which direction the moving object is going (This will easily make you miss a problem because you put a (+) instead of a (-). Be sure you put the correct velocity in your formulas, and WATCH YOUR UNITS! I missed several because I didn't convert my answers correctly. Good Luck:) Alex Stuart

In this chapter it contains everything about the potential energy and kinetic energy. It shows how and why they are equal to each other and gives you a better understanding of how forces and velocities work when people and items have head on colisions. I found this chapter to be very interesting. You need to make sure you read each problem completely and think and visualize what is actually happening. In the total momentum problems it says to have the answer in kg(m/s). That is exactly how you work it. Mass times Velocity. Also, the other equations I used was: mass of 1st item times its intial velocity plus mass of 2nd item times its intial velocity is equal to the mass of the 1st item times its final velocity plus mass of the 2nd item times its final velocity. It seems long and hard but its not. (Hint: when the final velocity is the same for the two items because the are stuck together from impact you can simply make the equation equal to the mass of the 1st item plus mass of the 2nd item times the final velocity. Its really not that hard. Don't over think the problems. If you have questions just ask. Good luck. CSpears

This chapter in my opinion is just a more in-depth look at the last chapter work and energy. - m1v1i+m2v2i=m1v1f+m2v2f this formula solved almost 2/3 of my packet because there are so many ways to get it to equal what you need. It helps to be creative about the equations. Most of the time in conservation of motion problems it will not tell you what is not moving so just assume and put the Initial velocity as 0 because whatever the object is it is most likely at rest. In the problems be sure to label everything for what they are and make sure to put numbers that are supposed to be together, together. The labs are word for word and make sure to do a Print Screen for each lab. (Word has to be opened to do this and to get the print all you do is paste it). The book is also probably the best tool to use when working this packet because there will be similar problems and you can work and see if you are on the right track. Remember that KE=1/2mv^2 and to get the total KE you will have to do 2 separate problems and then add the answers together to get total initial and final separately. I also have an opinion on how to work the problems.... I was able to finish my packet in a few days by working them in chronological order because then you won't save all the hard problems to the end and then you won't become stressed over them. It helps also because there are a lot of similar problems throughout the pack. Just work as the problems come and stay focused. Hope it was helpful, RachelT
