Does a rock sitting on a hill have energy why?
It has potential energy that can be released by starting it rolling down the hill so that the potential energy is converted into kinetic energy and friction with the surface.
What type of energy is a frog sitting on a lily pad kinetic?
The energy is potential energy
What are some ways people use kinetic and potential energy?
its like your sitting in a chair potential then u get up and do something like move the chair kinetic
What would the kinetic energy of a rock sitting on the ground be?
Zero. You need to think in terms of "frame of reference" as in what are you comparing the rock to. If you are an observer sitting next to the rock then the kinetic energy of the rock RELATIVE TO YOU is zero - I.E. the rock isn't moving relative to you and thus has no kinetic energy - energy of motion - relative to you. If you are an observer sitting a million miles from earth watching the rock then it is zipping around at 1000 miles per hour as the earth spins on its axis and it has significant kinetic energy RELATIVE TO YOU.

Is there energy in an ice cube?
yes... if it is just sitting there, it has potential energy..... if it is falling into a glass, it has kinetic energy
What are the relationships between potential energy and kinetic energy?
People can improve me, but kinetic energy is the energy of motion and particles speed of a substance. So in otherwords if you had a textbook sitting on the table, it has potential energy, but if you push it off the table it then sort of has kinetic energy.

A squirrel running up a tree and sitting on a branch shows what kind of energy conversation (apex)?
Kinetic energy becoming potential energy.
Can kinetic energy be a balanced and appear to not move and if so what are some examples?
No, not the way you're trying to describe it. But the kinetic energy of a moving object can appear to have different values, depending on how the observer is moving when he measures it. Example: I'm sitting comfortably, reading a book. I doze off, and the book settles down in my lap. What's the kinetic energy of the book ? To the person sitting next to me, the kinetic energy of the book is zero, because it's not moving. But that person and I are sitting in adjacent seats on a transatlantic flight to Europe, cruising along at about 500 mph when I doze off. The scientist down there in his boat, watching us fly over, would not agree that my book has no kinetic energy.
A bowling ball striking the pins is kinetic or potential energy?
This is considered kinetic energy because it is moving. If it was potential energy, it would be just sitting, with stored energy.
Does pushing a pen off a desk converts potential energy to kinetic energy?
Yes. When the pen is sitting on the desk, it has the most potential energy. Once you move the pen, its potential energy is transformed into kinetic energy.
Give an example of friction?
Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.
