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.

When you lift an object, the energy transferred to the object is called gravitational potential energy.



Yes. The energy of lifting is added to the object as potential energy. If the lifted object is then released, it will fall, and the potential energy will become kinetic energy.


it is by changing the direction of the input force on the object on studyisland


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.


Chemical energy (originally form the Sun) in your muscles is used to impart potential energy to the object you have lifted.


Potential (gravitational) energy is transformed into kinetic energy. So, for instance, if you lift an object, you're storing energy which will act on the object once you let it go (increasing velocity).


Air cannot do that alone. Airplane wings are shaped such that a forward motion will force them to lift.


If we use a inclined plane to lift a object then the amount of energy used decreases applied force and wok


Potential energy is energy done to place something somewhere, against a force (not any force, it must be a so-called "conservative force", but I am only mentioning this for completeness sake). Specifically, gravitational potential energy is the energy an object has when it is raised above ground level. You need to supply energy (as work) to lift it up; in theory, this energy can be recovered if the object falls down.


it reduces the work by making an object easier to carry or lift to a higher or lower ground


It reduces the rate of work needed to lift a load or an object.The total energy should be the same, inclined plane or direct lift of that object.


Yes. It is easier to push an object up a plane than lift it straight up. It does not reduce the total amount of energy needed to lift it up.



Energy can neither be created nor be destroyed. When we lift certain thing to a certain height we have to done some work on it . This energy is stored in the form of potential energy. Potential energy = mass * acceleration due to gravity * Height of object from ground. As height increases PE increases.


yes. a hurricane can lift a houso out of the ground.


450 Joules of energy are needed to lift a 15 kilogram mass 3 meters off the ground.


Lifting an object to a greater height requires more energy, but not any more force, thanlifting it to a not-as-great height.


The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

A screw jack is an object that is used to lift the car and other heavy objects off the ground.


Faster-moving air exerts less pressure, so there will be force (lift) generated by the air below the object. This is the principle of powered heavier-than-air flight. The object will have a area of low(er) pressure in top than air underneath, causing lift. This is cause by the air on top being stretched out and having lower density or pressure then the bottom. If there is enough lift to counteract the weight of the object, the object will lift off the ground.


Whenever work is being done, energy is changing from form to another, so the shortest answer is "by doing work". As an example, If you lift a brick from the ground to a shelf, the work you do - muscle energy - is converted to potential energy in the brick. If you then push the brick off the shelf, it crashes to the ground and that potential energy changes to kinetic energy as it falls, and to sound and brick smashing energy when it hits the floor. Avoid toe breaking energies and don't try this at home.


Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.


It requires energy to lift an object against the force of gravity, and this energy can be recovered (for example, converted to movement) if the object goes back down, so it makes sense to think that the energy went somewhere.


Because the heavier an object is, the more force is required to lift it off the ground. So, by having light bodies, animals that can fly reduce the amount of energy they need to use to be able to fly.
