I am in need of some basic tools in which to become better prepared to excel in my "Conceptual Physics" college course. I am a retired veteran of the Army and have not been in school for 25 years. Some reference charts for Trigonometry, basic glossary for any terminology, YouTube videos,etc.....??? I am struggling with my homework. Suggestions please. Thanks
Eric
Eric, I'm not sure what you need, but if it's Physics tuition (or Math)try Khan Academy. Hundreds of short vids.
Hope Jiskha don't mind this post.
Real life experience:
I am not exceptional in math but I have managed to learn chemistry by using only a couple books and the internet. I spend hours on my smartphone with practice questions and homework questions that I've found on the net. I'm not even a student in a school but I have been surprised by the amount of knowledge I've gained. I really think your best bet is a couple of testing books/textbooks from the school or bookstore and then use the net. If you don't like studying in a closed room, you can take your smartphone to a park or a scenic area and this will make it fun! Many sites for chemistry such as chemteam have problems with all the answers and explanations, and I am sure the same is going on for physics.
A barge is hauled along a straight-line section of canal by two horses harnessed to tow ropes and walking along the tow paths on either side of the canal. Each horse pulls with a force of 490 N at an angle of 16° with the centerline of the canal. What is the net force on the barge?
15 N
Hi Eric! It's great to hear that you're taking on the challenge of studying conceptual physics. Here are some suggestions for resources that can help you excel in your course:
1. Textbooks: Look for a recommended textbook for your course. It will likely have explanations, examples, and practice problems that can aid your understanding of the concepts.
- To find a relevant textbook, check your course syllabus or ask your professor for recommendations.
2. Online resources and videos:
- Khan Academy (https://www.khanacademy.org/) offers a wide range of educational videos and practice exercises, including topics like trigonometry and basic physics concepts.
- Crash Course Physics (https://www.youtube.com/playlist?list=PL8dPuuaLjXtN0ge7yDk_UA0ldZJdhwkoV) is a series of fun and engaging YouTube videos that cover various physics topics.
- MIT OpenCourseWare (https://ocw.mit.edu/courses/physics/) provides lecture notes, videos, and problem sets from actual physics courses at MIT.
3. Glossaries and reference charts:
- Many physics textbooks come with glossaries that define key terms. Make sure to refer to them when you encounter unfamiliar terminology.
- You can also find online glossaries that offer definitions and explanations of common physics terms. A simple internet search with the term you want to define can be helpful.
4. Practice problems and worksheets:
- Practice is crucial for grasping physics concepts. Look for resources like textbooks, online problem banks, or worksheets that provide practice problems with solutions.
- Websites such as Physics Classroom (https://www.physicsclassroom.com/) offer online tutorials, simulations, and practice problems.
5. Study groups or tutors:
- Consider joining a study group to collaborate with classmates who may have different perspectives and approaches to solving problems.
- If you're still struggling, seek out a tutor who can provide personalized guidance and assistance.
Remember that mastering physics takes time and practice. Break down the material into smaller, manageable chunks, and be patient with yourself. Good luck with your studies!
