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?

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.
Does kenetic energy exceed Gravitational potential energy?
Yes, in most cases kinetic energy exceeds gravitational potential energy because kinetic energy is associated with the motion of an object, while gravitational potential energy is associated with the height of an object in a gravitational field. As an object moves, it typically gains kinetic energy and its gravitational potential energy decreases.
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. The book in the higher position has more potential energy.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. The book in the higher position has more potential energy.
If the Kinetic Energy equals five what would the Potential Energy equal?
The potential energy would be equal to five if the kinetic energy equals five. This is because in a closed system, the total mechanical energy (kinetic energy + potential energy) remains constant. Therefore, if one form of energy increases, the other form of energy must decrease to maintain the total constant.
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.
What are two examples of micanical energy?
Two examples of mechanical energy are the swinging of a pendulum and the motion of a moving car. In both cases, the energy is associated with the movement of objects.
How much potential and kinetic energy does an average person use a day?
An average person uses about 2,000-2,500 calories per day. This energy is primarily in the form of potential energy stored in food and converted into kinetic energy for various activities such as physical movement and cognitive functions.
Where does lost potential energy go?
Lost potential energy is typically transformed into other forms of energy, such as kinetic energy, heat, or sound. For example, when an object falls from a height and loses potential energy, it gains kinetic energy as it moves faster. In most cases, the energy is still conserved according to the law of conservation of energy.
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?
Yes, kinetic energy can be converted into potential energy. For example, when a moving object comes to a stop, its kinetic energy is transformed into potential energy. This can happen in various situations such as when a pendulum reaches its highest point or when a car stops moving up a hill.
If total (PE plus KE) is conserved?
When the total mechanical energy (potential energy + kinetic energy) of a system is conserved, it means that the sum of the kinetic and potential energies remains constant over time. This implies that the system is isolated from external forces that could alter its energy. In such cases, the energy transformation between potential and kinetic energies can occur without any net loss or gain in the total mechanical energy of the system.
