Start a Physics Astronomy Club: Ideas Advice The discussion revolves around starting a physics and astronomy club at a high school, focusing on ideas for activities, projects, and outreach strategies Participants share suggestions for engaging projects and resources that could attract members and enhance learning in physics and astronomy One participant suggests activities like building a mini particle accelerator or hoverboard
Why does electric potential energy increase if you move against the . . . My understanding of this question is that, if you have a proton standing against a positive electric field, and move it in the opposite direction of the field, you're putting in work and therefore should have greater electric potential energy But that idea breaks down when you consider a
Torque seesaw problem- rotational equilibrium - Physics Forums The discussion revolves around a seesaw problem involving rotational equilibrium, where one block is positioned to the left and another to the right of the fulcrum The original poster seeks to determine the mass of the second block and the force exerted by the fulcrum, expressing confusion about the role of normal forces in the equilibrium equations Exploratory, Assumption checking, Problem

Learn How to Solve the Cubic Equation for Dummies Everybody learns the “quadratic formula” for solving equations of the form A x 2 + B x + C = 0, even though you don’t really need such a formula, because you can solve for x through the technique of “completing the square” What you need a formula for is the solution to the cubic equation: A x 3 + B x 2 + C x + D = 0 There is no obvious way that “completing the cube” makes the
Floating Rotation above computer fan • Physics Forums The discussion revolves around the feasibility of making a piece of paper float using the airflow from a computer fan Participants explore the dynamics of air velocity around the fan and whether it can create sufficient lift for lightweight objects The conversation touches on concepts of airflow, drag effects, and the mechanics of fan operation One participant suggests that the air velocity
