Thank you! It is very clear now :)

yes thanks !

Oh great! yes it helps! Thanks :D but in the example u said, I do work ON the bucket but the bucket doesn't do any work right? or am I understanding it wrong?

I was just confused now. Is there work being done if I lift a bucket of water straight up? I know there is something about "work being done BY the bucket" and "work being done ON the bucket". Since I'm not moving horizontally does it mean that no work is done on the bucket? But I'm still...

Oh thank you :) I still seem to be going in circles. I made a table with the kinetic and potential energies for each one: (by the way the speeds are supposed to be in cm/s - i typed it wrong) 1) 0.39m/s --> Kinetic E = m(v^2)/2 = 0.018252 J Potential E = mgh = 0 J 2) Kinetic = 0.003072 J...

Homework Statement A 240gram toy car is driven by an electric motor that has a constant power output. The car can climb a 24° incline at 16m/s and can travel on a horizontal table at 39m/s. The frictional force retarding the motion is kv, where k is a constant and v is its speed. How steep...
