Explaining the Energy Transfer in a Chairlift's Start and Stop

AI Thread Summary
Starting a fully loaded chairlift requires more energy due to inertia, as it resists the initial change in motion. This initial energy is needed to overcome the inertia before the lift can maintain a constant speed. When the lift starts, energy transfers occur, converting electrical energy into mechanical energy, which then increases the gravitational potential energy of the riders. As the lift operates at a constant speed, it continuously adds potential energy to the mass of the riders. Ultimately, the energy dynamics involve overcoming inertia initially and then maintaining energy transfer as the lift operates.

Homework Statement


Propose an explanation for the following fact. Include a description of the energy transfers that would take place when the lift starts and stops.

A fully loaded chairlift requires more energy to start then it does to maintain motion.

The Attempt at a Solution


I thought that perhaps it takes more energy in the beginning because the chairlift has inertia and is resisting the change. You need to apply more energy to get over this initial inertia.

I'm having a hard time including energy transfers...

I know that when the lift starts riders gain gravitational potential energy, which eventually turns into kinetic energy on the way back down the hill..

Thank you !

When it's running at constant speed it's giving mass additional PE at a rate that depends on the speed.

But it has to get to that speed first so...
 
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 '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...
