Total energy of a body in a circular orbit

AI Thread Summary
In a circular orbit, a particle is influenced by a single central force, resulting in zero work done by the force since it always acts towards the center. This leads to the conservation of energy, allowing for the determination of potential energy at a specific radius. The centripetal force derived from the potential field is responsible for maintaining the circular motion of the object. The challenge lies in calculating the kinetic energy of the particle. Understanding these principles is crucial for solving problems related to total energy in circular orbits.

The Attempt at a Solution



Is the particle moving under the influence of a single central force ?

Since the force always acts towards the center , work done by the force is zero . Energy is conserved . Potential energy at a particular radius can be found . But how do we find the kinetic energy of the particle ?

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
