Hello all! I have a question on acclerating frames. The apparent weight of an object in an elevator that is accelerating upward is m(g+a), where g is gravity and a is the acceleration of the elevator. In my textbook they give an example of a crate placed on a scale at the equator. They want...

Okay I though that if the force was conservative, then the gradient could be used, I didn't know that it proves the force is conservative. A correction in the force equation F = -kx + ax^3 + bx^4 After integrating a found the potential equation to be U = (kx^2)/2 - (ax^4)/4 -...

Hello everyone, I have a question about conservative forces. I am given a function F = -kx^2 + ax^2 + bx^4, where a, b, and k are constants. I am asked to determine if this force is conservative or not, I don't know know how to prove this mathematically or theoretically. Please help! In...

Thank you both.

Okay, I must have been thinking in terms of the acceleration of the Earth towards the object. But I see from the equation now. If the moon were a baseball it would still accelerate towards the Earth with the same acceleration as the actual moon itself because r is fixed. The Earth would...

inertial and noninertial frames of reference Oh, I see, relative to the table the block has a vertical acceleration and a horizontal acceleration. Thank you! When I stepped away from the incline and onto the table, as I pictured it in my head, I could see the block moving up the inline...

Graivty The force of gravity does vary with distance from the center of the object, in this case the center of the Earth. The force of gravity between any two objects is inversely proportional to the square of the distance between the two objects. Just like light spreading as sperical waves...

Greetings fellow physicists! I am stuck on a problem, please help. The situation is a block on a rough incline (trainglular block), the incline itself is on a frictionless table. A horizontal force is applied to the incline. The question is to find the minimum horizontal force needed so that...
