1. ## What Is "movement" In Physics?

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
2. ## Time To Accelerate To Maximum Velocity Including Drag

Say I have an aircraft. I know it's thrust and the properties needed to determine its drag. The craft accelerates at at 10 m/s^2. Making the drag equal to the thrust, I determine its max speed to be 180 m/s. If I were to ignore drag, I could simply say it would take 18 seconds to reach maximum velocity, but I am attempting to determine how long it would take to reach 180 m/s including drag. As the velocity increases, the drag force with increase exponentially, so the net thrust/rate of acceleration would decrease each second. Is there a way to wrap F=ma with F=(CApv^2)/2 to determine the time
3. ## Is Wood Glue Really Stronger Than Wood? (Shear/axial/bending Stress Tests)

I read that wood glue is supposed to bond better than wood, which didn't jive with my physical intuition. I did some stress testing with various types of wood, and here are my results! https://www.youtube.com/watch?v=cGdhEQW3JdA&lc=z23ohj4hsle4iprkhacdp433zyovxftsqqtmvzjydmtw03c010c
4. ## Moments Of Inertia

Hi, I need some assistance understanding moments of inertia. I am doing some review for an upcoming exam, however I am slightly stumped by this question. I have already tried googling "moments of inertia" to try and understand the concept better, but I am having issues knowing when to apply which formulas. I have attached my specific question and the "answer" to the question, hopefully someone can help me understand how to get the answer. ---- Two identical slender rods of length l and mass m are linked together at 90deg, as shown in figure Q4a (image attached), to form a link in a mechani
5. ## Why Gym Workout Doesn't Work Out !

Hi ! THIS IS INTEGZA!! So lately I have been wondering about what makes a human physically strong, is the size of the muscles all that matters? In this video I approach a specific case of a pro armwrestler defeating a bodybuilder with apparently more muscle mass but in between I talk about the One Inch Punch, Shaolin Monks traning, Human metabolism and so on .
