What else can I help you with?
Can an object have energy when it is at rest?
Yes, an object can have potential energy when it is at rest, such as gravitational potential energy or elastic potential energy. Kinetic energy, which is energy of motion, requires the object to be moving.
What is the cats gravitational potential energy relative to the floor if the acceleration due to gravity is 9.8 m's 2?
The cat's gravitational potential energy relative to the floor isEp = m.g.hEp = (the cat's mass) x (gravity) x (the height of the cat's center of mass above the floor).Ep [=] Jmass,m [=] kggravity, g = 9.81 m/s2height, h [=] m
An example of gravitational potential energy?
Any object that is above the chosen reference level has gravitational potential energy. If your chosen reference level is the ground level, a book on the table, or you yourself if you are standing rather than lying on the floor, have potential energy.
How can you increase gravitational potential energy?
Potential gravitational energy is pretty theoretic, but exists as potential. So a ball sitting on the floor has little to no potential energy as it is as low as possible, but put that ball on a table, its potential energy increases. So the answer is to place things higher, on a surface of a sort. Mass and height
A ball held above the floor has what type of energy?
Any object above ground level has gravitational potential energy. Actually, ground level is commonly chosen as the reference level, but any other level may be chosen as well. The choice is arbitrary.

Which mass has the greatest gravitational potential energy with respect to the floor?
The one that is at the greatest height above the floor level.

How is two vases are side by side on a shelf one can have more potential energy?
Look at the formula for gravitational potential energy, which is mgh. If the vases have different masses, they can have different amounts of gravitational potential energy, even if their height above the ground (or another chosen reference level) is the same.
What device that transforms gravitational energy to kinetic energy?
Anything that falls. Some examples are: -- A waterfall -- A ball rolling down a hill -- A sailplane, when it is NOT climbing in a thermal -- Any pendulum, when it is moving TOWARD the center of its swing -- Anything you drop. The gravitational potential that it has relative to the floor while you're holding it in your hand is exactly the kinetic energy it has when it hits the floor.
Can gravitational potential energy be negative?
In potential energy, the important thing is the increase or decrease in energy; any absolute energy level is arbitrary. So, it all depends on what level is arbitrarily defined as zero. For example, if you define the floor level as zero, then anything above that will be positive, anything below that will be negative.
Is a book sitting on the top shelf potential energy?
A book, no matter where it sits, is an organized and bound assembly of paper with information stored on it. The book has some mass, and like any mass, its gravitational potential energy relative to the floor can be defined in terms of its mass and its distance above the floor.
Why does the ball gravitational potential energy increases from point b to a?
Working completely in the dark, I'll take a wild guess and say that point 'a' is higher off the ground or the floor than point 'b' is. I could be wrong. I'd have a better chance of guessing right if I could see the picture.
