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.

∙ 9y agoWhen an object is thrown upward, gravity is the force that acts upon it. Gravity will pull the object back down to the ground.

It's possible that you're trying to describe tidal forces, but that's not exactly "an upward force."

What device changes gravitational potential to kinetic energy?
The free fall of the object in gravitational field changes its gravitational potential energy to kinetic energy
An object's energy due to its relative position?
This is called potential energy. The most common form of potential energy is an object suspended above the ground. Its height gives it potential energy, which is defined as mgh, where m is the mass, g is the gravitational constant, and h is the height.
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.

Does an object mass change potential energy?

Potential energy is energy due to?
Potential energy is the energy that is waiting to be use. Such as when a boulder is sitting on top of a hill. The boulder has potential energy because it can be pushed down the hill. sara
How does an object get gravitational potential energy?
An object gets gravitational potential energy by
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.
Why when you push an object across a desk is the work done not equal to the change in gravitational potential energy?
The gravitational potential energy does not change if the desk is horizontal. The work done is in overcoming the friction between the object and the desk.
What happens to the potential energy of an object if the mass is halved?
I assume you mean the gravitational potential energy. This is proportional to the mass, so if you change the mass by a factor of "a", the gravitational potential energy will change by the same factor of "a".
When you lift an object energy is transferred to an object which gives the object?
When you lift an object, the energy transferred to the object is called gravitational potential energy.
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.
When you lift an object off the ground how are you changing its energy?
You are changing the object's gravitational potential energy. Gravitational potential energy is the energy due to position of the object above the Earth. This energy has the potential to be transformed into Kinetic Energy if the object falls.
How can you change the gravitational potential energy of an object?
Put it on a higher shelf. Or a lower one.
Does speed affect gravitational potential energy of an object?
Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed. Ep = mgh Energy Potential = mass * 9.81 (gravity) * height Speed / Velocity is absent from that equation.
Is there more gravitational potential energy in heavier object or lighter object?
When they're both at the same height, the heavier object has more gravitational potential energy.
What is the law of gravitational potential energy?
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.
What is the mathematical expression for gravitational potential energy?
Gravitational potential energy = (object's mass) x (acceleration of gravity) x (object's altitude)
