In physics, there are terms: mass, speed, acceleration, moment, force, work, energy, but nowhere has the term "movement". So I ask anyone who knows some physical law or equation in which a member of the equation is called a "movement" to let me know. Without that, I don't understand what "physics professors" think when they claim Sir Isaac Newton gave them "Laws of Movement"! So what is it? I was taught at school that Sir Isaac Newton gave us the "Law of Force" and the three principles (laws) on the operation of that Force. The most important principle we first learned was the "action and
(A question in grade 11 Physics paper.) Information given: Two blocks are connected to each other with a rope that runs over a frictionless pulley. The system is stationary/at rest. Coefficient of static friction between the 5.1kg block and slope surface is 0.3. The slope has an inclination of 27 degrees. Question: What is the mass of block B? My answer: First calculate maximum static friction of 5.1kg block: fs(max) = Fn * μs fs(max) = (5.1 * 9.8 * cos27) * 0.3 fs(max) = 13.3598...N Then calculate the gravitational force of the 5.1kg block parallel to the slope Fg(parallel) = Fg
Classical #physics predicts weight (W) should NOT change at increasing temperature (T) in vacuum. Relativistic #physics predicts W should INCREASE at increasing T in vacuum. My theory predicts W should DECREASE at increasing T in vacuum and can be found here yaniv-stern.webnode.com. W reduction at increasing T in vacuum disproves conservation of mass and most of the rest of #physics. Over the past ten years I contacted thousands of scientists to weigh a heated metal in vacuum and publish the results. I did Not get the results of the experiment. #ResultsRequired
Hi all, In school, we've been taught that while in space; we can float around and have no weight at all. You can float around, yes. Having no weight at all is an entirely different story. The formula for weight is what? : Mass * Gravity. Now if I'm to prove my point, I need to first prove that space isn't Zero-G (Zero Gravity). Let's for instance take the sun; all planets are in a orbit around it, due to? Yes, Gravity! So if for some reason you jumped out of your rocket, you won't leave the Galaxy. You'll just obtain an orbit around the sun unless you're accelerating at high levels. So
