Explain your thoughts about the problem and the steps you've taken so far. Provide those who help with as much information as possible. Demonstrate that you have already put in some thought and effort into solving the problem. If you post an essay for editing or other help, create a Google doc or similar. Walls-of-text are almost impossible to edit with any effectiveness. Be sure your doc is accessible to those who will read your essay.
Remove all personal information prior to posting. This subreddit is for help, pushes in the right direction, not answers. Think of this as an anonymous tutoring center. With that in mind, the moderators have sole discretion to remove any post they feel violates that idea.
Accept answers at your own risk. We use automoderator for a few things. It may delete a post erroneously. If your post is missing and you're sure it's not a rule-breaker, send us a note and we'll look into the issue. We ban all bots. I'm having some problems with my physics homework and I was hoping somebody could help me. The problems that are giving me problems are sorry about the unit vectors in the first problem, I didn't know how to do them on reddit. What is the instantaneous rate at which the force does work on the object?
At some other time, the velocity consists of only a j component. If the force is unchanged, and the instantaneous power is W, what is the velocity of the object just then?
The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically up position, with zero speed there.

The Teacher Toolkits provide teachers with packages of online resources simulations, movies, animations, demonstration ideas, etc. These resources, when combined with the numerous resources on our own site, allow teachers to plan high-quality, engaging instruction and to map out a curriculum that is NGSS-based.
The Science Reasoning Center includes teacher-friendly and classroom-ready resources for culturing your students' science reasoning skills. A resource CD is also offered to assist you in your efforts to develop a plan that both improves and assesses your students' abilities to interpret data, analyze experiments, and evaluate models and theories.
While you explore the approximately labs here at The Laboratory, you will likely generate some questions about how they are used and how you can use them. This page, and the pages it links to, are hoped to provide some answers to those questions. The Photo Gallery provides teachers a toolbox of physics-relevant photos from the wealth of photos on Flickr.
The Photo Gallery offers teachers three things: Of course, students are welcome to participate as well. More and more teachers are adopting The Physics Classroom as their textbook. We don't blame you if you do. You sure can't beat the price But once you join the club , its time to get your students on board. We're offering you a large collection of tools that you can distribute to students or post on your course page.
