A force can be apush or a pull. A force acting on a body tend to produce a change invelocityoraccelerationof the body. SI unitof force is thenewton (N). It is avector quantity. We can add/subtract forces. (More about this atAddition of forces) ...
Physics: Physics is the science that is concerned with studying the fundamental relationships that exist between all aspects of matter and energy. The matter is anything that has a volume and a mass. Key Ideas: There are two basic forms of equilibrium in Physics: Dynamic equilibrium (for obje...
In summary, my professor said that the moment of inertia of a system is equal to the sum of the moment of inertia of each of its masses. However, I don't see why we can use R here rather than the distance from the center of the pulley to the mass. Isn't the moment of inertia...
‘moment of’ in physics is used to depict the rotational counterpart of a linear quantity. Thus, the ‘moment of inertia’ is the rotational equivalent of mass for linear motion. It is denoted by‘I’. Similarly, the ‘moment of force’ is the rotational equivalent of linear force, also...

What is the resulting force the pilot feels when they just begin to pull up into the circle (they are at the lowest point)? Centripetal and Centrifugal Force In physics, centripetal force is the force the keeps a mass...
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
In summary, The conversation is about solving a problem involving finding the moment of inertia of a system with multiple rods. There is discussion about treating the farthest rod as a point mass and confusion over the mass per rod. The correct approach is to treat the farthest rod as a ...
$\begingroup$ Well, very good explanation, however you could effectively assign the proton as a Dirac particle and extract its effective spin magnetic moment given by the equation shown in the question. It is not by coincidence that both equations for the Bohr magneton and Nuclear ma...
The instantaneous speed is the limit of the average speed as the time interval approaches zero. When you look at a speedometer in a car, you are seeing the instantaneous speed. While you may have been going 60 miles per hour for a moment, your average rate of speed for ten minutes might...
