1. Who We Are
Physics Fundamentals (physicsfundamentalsinfo.com) is a free physics education website publishing explainer articles, interactive simulations and calculators. In these terms, “we”, “us” and “the site” mean Physics Fundamentals; “you” means anyone using the site.
2. Using the Site
You may use the site for personal study, teaching and research at no cost. There is no account to create and no paywall. You agree not to interfere with the site’s operation — no attempts to break, overload or gain unauthorised access to it, and no automated bulk downloading that degrades service for other readers. Ordinary search-engine crawling is welcome.
3. Educational Use and No Warranty
The content here is educational. We check every formula, constant and worked solution against standard physics references before publishing, and we correct errors when we find them — but we cannot guarantee that every page is free of mistakes, and the calculators are teaching tools rather than certified engineering software.
Do not rely on a result from this site for anything safety-critical, structural, medical, financial or legally binding without verifying it independently. The site is provided “as is”, without warranties of any kind, and we are not liable for loss arising from its use to the fullest extent the law allows.
4. Our Content and Your Rights to It
The articles, diagrams, simulation code and calculator implementations on this site are our copyright unless stated otherwise. You may:
- link to any page freely;
- quote a short passage with credit and a link to the source page;
- use our material in a lesson, lecture or study group with credit;
- embed a calculator or an interactive lab on your own site using the embed snippet we provide, keeping the attribution link intact.
You may not republish whole articles, sell our content, present it as your own, or remove attribution. For anything beyond the list above, email contact@physicsfundamentalsinfo.com — we usually say yes.
5. Contributions and Submissions
If you send us an article, a correction or a suggestion, you confirm it is your own work and you grant us a non-exclusive right to publish and edit it. We do not pay for unsolicited submissions unless we have agreed that in writing beforehand. See Write For Us for what we accept.
6. Third-Party Links and Services
We link to external references — textbooks, NIST, HyperPhysics, university pages — because they are useful. We do not control those sites and are not responsible for their content or their policies. The site also uses third-party services for analytics and email delivery; see the privacy policy for what that involves.
7. Newsletter
Subscribing is optional and you can unsubscribe from any email we send. We do not sell or rent email addresses.
8. Changes to These Terms
We may update these terms as the site changes. The “last updated” date at the top always reflects the current version, and material changes will be noted to newsletter subscribers.
9. Contact
