Tags Inertia Moment Moment of inertia Rotational dynamics 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 ...
Well, the big takeaways about rotational motion are that: 1) It has mathematical analogs in the world of linear or translational motion that make studying either one in the context of the other extremely useful, as it shows how physics itself is "set up"; and 2) the thing...
You may think of inertia as a mysterious force keeping you from doing something you have to do, like your homework, but that isn't what physicists mean by the word. In physics, inertia is the tendency of an object to remain at rest or in a state of uniform motion. This tendency is ...
What is a Dyson Sphere? Discussion Comments Byanon130553— On Nov 29, 2010 @anon59262: I am only a Junior (high school) student, and I have been having trouble with our physics text book so I went here to get a bit more insight into inertia. However, I think that the moment of in...
Angular momentum is similar to linear momentum, except that it also takes into account the distribution of mass around the point of rotation. In physics, it is defined as the product of rotational inertia and angular velocity: Rotational inertia, also called moment of inertia, is concerned with...
Physics students should be comfortable applying rotational motion formulas. Review the definition of rotational motion and practice using the relevant formulas with the provided examples. Related to this Question What is the actual meaning of the moment of inertia?
Reactance is the property of an electrical component to oppose the change in current while impedance is the combination of resistance and reactance. There are two types of reactance: Capacitive & Inductive
In physics, a rigid body is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on arigid body remains constant in timeregardless of external forces exerted on it. ... Non rigid body is a substance which can be compressed...
The science of physics deals with movement and motion. Acceleration, or the measurement of the change in speed over time, is one type of movement or motion that physics addresses. Think of a car pulling out of a parking space onto the road. Over an amount of time, the car speeds up, ...
used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun is a centripetal force that keepsEarthorbiting ...
