When it comes to the math for phyics I start out by asking the class, "Who in here can not do math?" Completely aware of course they had to pass the math portion of an entrance exam to get into the school. When the hands shoot up, I just prove them wrong. "2 + 2=? 2 X 2=? A + B= C. If A=2 and B=2 C=?" As they answer the questions with ease, I will say, "So you can do math after all." Then they usually will say, "Yeah, but thats easy stuff. Thats not physics." I just smile and say "Really?" as I write a formula on the board and give them the variables. They all punch the numbers into the calculator and give the right answer. I then inform them that they just did a physics problem and there is no more BS about not being able to do math and cant do physics as I start teaching them why we are doing this, what am I catually trying to find, what information do I need to gather in order to find it, and where that information belongs in the formula. After doing alot of practice, those that really try start to get it, those that don't want to do it will keep finding excuses. Some of them try to convince me that not liking to do math is the same as not being able to do math. I just chuckle. Good Luck, Everyone!
