If a raised object has potential energy does it have more if you lift it higher?

Yes. The potential energy of an object is E=mgh where m=mass, g=acceleration of gravity (9.8 m/s^2) and h is the height of an object above a reference point. So, if two objects (on the same planet) have the same mass, the one that is higher will have the larger potential energy.
Another way to think of this is that in lifting an object higher you do work on that object. That work is converted into it's potential energy. Whenever you do work you change the energy of the object.

What is the source of potentail energy?
Let's take an example: gravitational potential energy. An object has more potential energy if it is raised to a higher position. The energy comes from whatever raised it up, although it is also possible (as in the case of meteorites) that the object was never on the ground in the first place.Let's take an example: gravitational potential energy.

True or false does potential energy depends on height is gravitational potential energy?
It is true that an object has more potential energy as it is raised higher. ?As the object falls from a height, the force of gravity will convert the potential energy into kinetic energy. ?The further it falls, the more kinetic energy will be gained. ?Conversely, the higher an object is raised, the more potential energy it has.This follows the equation? work = force x distance that force movesTherefore, the higher an object is, the greater the distance that the force of gravity will move as it accelerates the object while it falls. ?As it approaches the ground, it will have lost all potential energy but it will have kinetic energy of the same amount.Important note: ?The discussion about all potential energy being converted to kinetic energy above ignores air resistance. ?In the real world, air applies a frictional force on a body and will have the effect of slowing the object. ?Therefore, some of the potential energy will actually be turned to heat rather than ?kinetic energy. ?Most school physics questions will also ignore resistance due to air and therefore the description above works perfectly well for almost every question that will be seen.
When electrons are raised to a higher energy level they?
the dense of that element get lower when changing phrase
Why is potential energy called stored energy and into what kind of energy does it usually change to?
potential energy is found in things like a compressed spring, or a weight that has been raised to drive a clock. In it's static position, before the energy is released, it is being "stored". It usually changes into "kinetic" energy, causing something to move, or giving it momentum. Some of that energy will also be consumed by friction in the mechanism creating thermal energy.
When does an object have the same potential and kinetic energy?
When it is not moving or think of it like this when you climb a cliff when your on the top you have potential energy but as you climb down you are starting the state of kenetic energy. Therefor potential energy is when you are not moving. Or when energy is stored.
Is the gravotational potential energy more less or unchanged when the CG of an object is raised?
When the CG of an object is raised, gravitational potential energy increases due to a higher positioning from the ground, and therefore a higher "potential" to fall.

What is the definition of Gravitaitional Potential Energy?
The energy stored in a raised object.
The energy of position is what kind of energy?
That is called potential energy. For example, in the case of gravitational potential energy: If an object is raised, its potential energy increases.
How does potential energy gain?
Elastic potential energy is gained the more it is stretched (like a catapault or rubber band) Gravitational potential energy is increased if the object is raised higher up (further away from the centre of gravity)
What energy is a rock on top of a hill?
Gravitational potential energy is the type of energy stored in an object if it is raised in a gravitational field. A rock on top of a hill is a good example of this as it has a higher potential energy than a rock at the bottom of a hill.
How do you find potential energy?
gravitation potential energy can be found by the formula EP=mgh, where EP potential energy, m is the mass of the object for which the potential energy is to be found,g is the acceleration due to gravity, h is the height to which the object is raised.
Describe three situation in which the gravitational potential energy of an object change?
An object is raised higher, an object falls to a lower height, and the mass of an object above Earth's surface changes.
What is the connection between kinetic energy and potential energy?
When potential energy and kinetic energy are combined it is called mechanical energy. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
What are Non examples of mechanical energy?
Potential Energy. That is, Energy of Position. An Object raised to a greater height than its original position will show an Increase in its Potential Energy.
