If an object is thrown up in the air how does its gravitational potential energy change?
If the objects only source of thrust is the hand, it does not accelerate, it decelerates due to friction and resistance.
Answer:
The object accelerates as it is propelled upward and is still in contact with the hand. This cannot be determined without data on the velocity at which it leaves the hand. The formula used is:
a=vf - vi / t
where a is acceleration
vf is final velocity
vi is initial velocity
and t is time taken
Once free it accelerates negatively at the gravitational constant "-g" (-32 ft/sec2). Upon reaching the apex of its trajectory it accelerates downward at g=32 ft/sec2 until it strikes the ground. If the object is thrown in an atmosphere the apex of the trajectory is reduced by drag and the downward velocity reaches a maximum at the object's terminal velocity.

Is gravitational energy kinetic?
Gravitational potential energy is a form of potential energy, not kinetic energy. It represents the energy stored in an object due to its position relative to a gravitational field. However, when that potential energy is converted into kinetic energy as the object falls, it can lead to movement and activity.
Is Gravitational potential energy a type of kinetic or potential energy?
Gravitational potential energy is a type of potential energy that is associated with an object's position in a gravitational field. It represents the energy stored in an object when it is raised to a certain height above the ground.
Potential energy related to an objects height?
The potential energy of an object at a height is due to its position relative to the ground. This type of potential energy is called gravitational potential energy, and it increases as the object's height above the ground increases. The formula to calculate gravitational potential energy is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height 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.

Is the ratio of an objects mass to its volume called potential energy?
No, the ratio of an object's mass to its volume is called density. Potential energy refers to the energy stored within an object due to its position or condition, such as gravitational potential energy.
What two ways can you change the gravatational potential engergy of an object?
You can change the gravitational potential energy of an object by altering its height or the strength of the gravitational field it is in. Increasing the height or the strength of the gravitational field will increase the gravitational potential energy, while decreasing either will decrease the gravitational potential energy.
Energy at a height is called what?
Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.
How can you change the gravitational potential energy of an object?
You can change the gravitational potential energy of an object by changing its height relative to the surface of the Earth. Increasing the height will increase the gravitational potential energy, while decreasing the height will decrease it.
Can a objects mechanical energy be equal to its gravitational potential energy?
Yes, an object's mechanical energy can be equal to its gravitational potential energy. Mechanical energy is the sum of an object's kinetic and potential energy, and gravitational potential energy is a type of potential energy determined by an object's position in a gravitational field. When the object is at rest or its kinetic energy is zero, its mechanical energy will equal its gravitational potential energy.
Which does not affect the gravitational potential energy of an object?
The mass of the object does not affect the gravitational potential energy. Gravitational potential energy is determined by the object's height and the acceleration due to gravity.
How does an object get gravitational potential energy?
An object gains gravitational potential energy when it is lifted against the force of gravity. The energy is stored in the object's position relative to a reference point, such as the ground. The higher the object is lifted, the more gravitational potential energy it possesses.
What Does not affect the gravitational potential energy of an object?
The mass of the object does not affect its gravitational potential energy. Gravitational potential energy depends only on the height of the object above a reference point and the strength of the gravitational field.
What happens to the potential energy of an object if the mass is halved?
If the mass of an object is halved, its potential energy will also be halved as potential energy is directly proportional to the mass of the object. This is because potential energy is determined by the mass of the object, the acceleration due to gravity, and the height at which the object is located.
When does an object have gravitational potential energy?
Well gravitational potential energy is potential energy that depends on the height of an object so an object would have gravitational potential energy when ever it's of the ground or at a high height (it doesn't have to be very high) for example if you lift up a ball it has the potential to fall or if your climbing a mountain you have gravitational potential energy.
How is kinetic change to gravitational energy?
Kinetic energy can be converted to gravitational potential energy when an object gains height. As the object moves upward against gravity, its kinetic energy decreases while its gravitational potential energy increases. The total energy (kinetic + potential) of the object remains constant in the absence of external forces like friction.
Why when you push an object across a desk is the work done not equal to the change in gravitational potential energy?
When you push an object across a desk, the work done accounts for the change in kinetic energy of the object from rest to a certain velocity. The change in gravitational potential energy is not considered in this scenario because the desk is generally at a constant height, so there is no change in the object's position relative to gravity.
Can an objects mechanical energy be equal to its gravitational potential energy?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
