Are gravitational potential energy and kinetic energy equal in all cases?

They're hardly ever equal.
One of the few situations where they're equal is when you drop a weight to the ground
from some height. Then, the gravitational potential energy and kinetic energy are equal
when it's exactly in the middle of the drop, and the kinetic energy it has when it hits
the ground is the same as the gravitational potential energy it had when you let it go.

Why is g called the universal gravitational constant?
Why g is called the universal gravitational constant.Answer:Because it's the constant in Newton's Law of Universal Gravitation.It's "gravitational" because it is related to gravity; "universal ... constant" because it is the same in all cases."Universal" because it applied to the whole of the Universe.Another answer. But, g isn't called the universal gravitational constant.g is the acceleration due to gravity on our planet only.= 9.81 m s-2The universal gravitational constant is G (often called big G ) = 6.673 x 1011 m3 kg-1 s-2.It appears in Newton's equation f= Gm1m2 / d2 .
What information do i need to find the force of an object?
An object, in itself, does not have any force. It can exert a force on another object, such as gravitational or electro-magnetic attraction or repulsion, or from impact. However, in all such cases, you require two (or more) objects: one object, in isolation, exerts no force.
Is five mistake for every hundred a acceptable number?
In some cases, even one in a hundred may be unacceptable. In other cases, a larger amount of mistakes may be acceptable.In some cases, even one in a hundred may be unacceptable.

IF a case holds 12 items how many cases would you need to transport 159 items?
14 cases. The 14th case would not be full.
If the Kinetic Energy equals five what would the Potential Energy equal?
Kinetic energy and potential energy are not usually proportional. In the general situation, you can't derive potential energy from kinetic energy. In specific cases, sometimes you can - especially if you assume that potential energy that existed previously got converted to kinetic energy, or vice versa.Kinetic energy and potential energy are not usually proportional.

Would a book on a table one meter above the floor have more kinetic energy than a book resting on a floor?
No. Kinetic energy would be zero in both cases. The book in the higher position has more potential energy.No. Kinetic energy would be zero in both cases.

What do gravitational potential energy and chemical potential energy have in common?
In both cases, energy is involved in pushing something against a force.
What are the Similarities of kinetic and potential energy?
Only that both are energy - which can, in many cases, be converted from one type to another.
How much potential and kinetic energy does an average person use a day?
no In most all cases, yes. You use kinetic energy (energy due to motion) if you move, or if you move something. The most common form of potential energy is gravitational potential energy (basically energy due to height). You use this if you fall down (or fall into your bed) or if you drop something (even if it's dropping your backpack from two inches off the ground). You use gravitational potential energy when you drink from a cup by letting gravity do the work of moving the liquid down. It can also be argued that chemical energy is potential energy, in which case, you use it when you eat and obtain energy from food.
What is the relationship between the gravitational potential energy of an object and the work done on the object by the gravitational force?
I would have described them as different types of energy, so don't see what the relationship could be. If you hit a ball high in the air, it will have elastic energy stored in it from the initial blow, and it will also gain gravitational energy as it rises. The gravitational energy arises because the ball was given kinetic energy when it was hit, the elastic energy because it was deformed, but I don't think they then interact.

Does an apple have energy and why?
An apple has potential energy when it's just sitting on a table. If you pick it up, then it has gravitational energy as gravity is pulling it down. If you bite it, it releases chemical energy to your body. And if you throw it, it now has kinetic energy. :)
Can kinetic energy become potential energy?
Energy is never created or destroyed, but different forms of energy can be converted into another. For example, potential energy is the energy of position; a pendulum at the peak of its swing, or a spring tightly compressed. It can be converted into kinetic energy, for example, the pendulum swinging rapidly at the bottom of the swing, or the object propelled by the spring.
What does energy transformer mean?
An energy transformation is the change of energyfrom one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.
Where is the greatest amount of potential and kinetic energy in a roller coaster?
If it is a rollercoaster that has a first drop hill, the roller coaster has the greatest kinetic energy at the bottom of that drop. If it is magnetically launched, the kinetic energy is probably greatest immediately after the launch. However, there are cases where these statements may not be true. (i.e. a drop right after a magnetic launch)The energy is the greatest at the bottom of a drop, before some is translated back into potential energy as the car climbs the next rise.
What was the driving force of water?
Generally when water is used as a source of energy it is either the kinetic energy of the flowing water or the potential energy of the water as it changed height that was used as the energy source. In both cases it is gravity that is the ultimate driving force that makes the water move (for kinetic energy) or is the source of the potential energy - which is recovered as the water moves from higher to lower.
How do find gpe when you have velocity?
Assuming the object is travelling vertically (up/down) exclusively:The upward motion comes from kinetic energy, which is dependent on velocity. That kinetic energy is converted to potential energy, so you can set kinetic energy equal to potential energy.Let U = potential energy (in Joules), K = kinetic energy (in Joules)U = mgh, where m is mass, g is the acceleration of gravity, and h is heightK = (1/2)mv2, where v is velocitySolve for U:U = KU = (1/2)mv2That is thesimplestcase. Velocity is a vector (meaning it has direction as well as a magnitude) and it could be moving in a diagonaldirection. You'll have to use yourtrigonometryknowledge to solve these cases.
