Physics Help Books: Recommendations & Formulas

[clair_a_net]

Does anyone have a reconmindation for a physics help book, because i am currently taking phy 121 @ ASU and the TA tend to make things more confusing then making them understandable.

Also does anyone have an easy way to remember fromulas such as acceleration @constant speed, velocity @ constant speed and such, because I'm having trouble remebering them of the top of my head for quizes.

thanks

Most of us don't know what exactly phy 121 @ASU is. Is it a mechanics course? Is it calculus based? As for those formulas, I think you mean to re-word them. Acceleration at constant speed is zero if the particle is not changing direction, and if it is then this is kind of a very riddle-ish way of asking for the formula $a=\frac{v^2}{r}$ where r is the instantaneous radius of curvature. Likewise, velocity at constant speed is just the initial velocity if the particle is not changing direction, and if it is changing direction, then the velocity is just whatever it happens to be; there's no way of telling. In general a good way of remembering formulas is remembering how they are derived.

As a fellow scientist, I understand the struggle of trying to remember formulas and concepts in physics. I would recommend checking out "Fundamentals of Physics" by Halliday and Resnick or "University Physics" by Young and Freedman. These books are widely used in introductory physics courses and offer clear explanations and examples to help you understand the material.

In terms of remembering formulas, I suggest practicing with them regularly and creating your own study aids, such as flashcards or cheat sheets. Additionally, understanding the underlying principles behind the formulas can also help with retention and application.

I also encourage you to reach out to your professor or other resources on campus, such as tutoring services, for additional support in understanding the material. Physics can be a challenging subject, but with persistence and the right resources, I am confident you will succeed. Best of luck in your studies!
