What Happens to Your Kinetic Energy on a Continuously Moving Ski Lift?

AI Thread Summary
On a continuously moving ski lift, the energy dynamics involve both kinetic and potential energy. As the lift ascends, kinetic energy is converted into potential energy, indicating that the skier is gaining height. The discussion highlights the importance of the reference frame when considering energy types, as the lift's movement implies ongoing kinetic energy. Additionally, the ski lift does work on the passengers, facilitating this energy transformation. Overall, the scenario illustrates the interplay between kinetic and potential energy during the ascent on the ski lift.

Homework Statement



You're on a ski lift which moves continuously. If you are on a chair at the base of the mountain beginning to head up, is it potential energy or kinetic energy?

The Attempt at a Solution



From my viewpoint, this is kinetic energy being converted into potential energy as you climb the mountain on the lift. However, The question is rather confusing in nature.

You have to elaborate the "it" part.
 
Answer me this:

Did you do any mechanical work?
Did the lift do some work on you?

Be careful about the reference frame in which the energy consideration is asked.
 
Depending on your reference level, you will retain some potential energy...but, disregarding that, a lift tends to lift people up, so they are heading for higher potential energy. If you are heading for higher potential energy, you will need kinetic energy to get there.

Since the ski lift moves "continuously", what does that say about your kinetic energy?
However, The question is rather confusing in nature.
Agreed. Did you present the question word-for-word exactly as given to you?

This is not a simple case of mechanical energy being conserved. (Something is pulling the ski lift up the slope.)
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
