Potential work = gravitational potential energy = mass x gravity x height = 20 x 9.8 x 10 = 1960 J or 1.96 kJ

How much work is required to lift a 3.1 kg concrete block to a height of 1.6 m?
48.6
How much work is done when a block of woof is lifted with a force of 10N to a height of 4m?
Work = (force) x (distance) = (10) x (4) = 40 joules
How much work is done if the mass 3.0kg lifted 40 meters?
work is equal to a change in energy. in this case there is a change in potential energy. potential energy = mass x gravity x height E(p)=mgh E(p)= 3x9.8x40 E(p)=1176 J thus there is a change in potential energy of 1176 joules and since W=change E(p) Work done is 1176 J
How much work is done when lifting a 10 kg mass up a distance of 20 m?
Use the formula for potential energy: PE = mgh (mass x gravity x height). Since you are using SI units, use 9.8 for gravity.
How much work is done to roll a 40 kilogram barrel up a 10 meter long ramp to a height of 5 meters?
If we can neglect friction and the inefficiency of human physical effort, thenthe length of the ramp doesn't matter. In rising 5 meters, the barrel gainsm g h = (40) (9.8) (5) = 1,960 joules of potential energy,so that's the work required to lift it to that height, no matter the route ormethod selected.
How much work is required to lift a 4.8 kg concrete block to a height of 1.7 m?
Use the formula for gravitational potential energy (mgh).

How do you calculate the work of a block on an incline?
the work performed is the weight of the block times the height, or rise, of the incline
How can the gravitational potential energy of an object be changed?
Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work.
What is the relationship between the work done while moving a book to a higher bookshelf and the change of potential energy?
It is the same - work done is weight x height and potential energy change is the same at the new height
How much work is done when a block of woof is lifted with a force of 10N to a height of 4m?
Work = (force) x (distance) = (10) x (4) = 40 joules
How is work related to gravitational potential energy?
As we lift a body of mass m from ground level to a height h, then work performed will be mgh which is equal to the difference in gravitational potential energy at the ground level and at that height.
What energy of a book on a shelf is equal to the work done to lift the book to the shelf?
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
How much work is required to lift a 3.7kg concrete block to a height of 2.2 m?
(Mass) x (acceleration of gravity) x (height) = (3.7) x (9.8) x (2.2) = 79.772 joules
How much work has done to lift a 1000 kg block?
That depends how high you lift it.The work is mgh (mass x gravity x height). If the mass is in kilograms, gravity is in newton/kilogram (Earth gravity is about 9.8 newton/kilogram), and the height is in meters, then the work will be in joules.
Why is potential energy sometimes called stored energy?
because the work done in placing that object at a height is stored in it as the potential energy....
Why is potential energy called gravitational potential energy?
Potential energy and gravitational potential energy are different from each other ."Potential energy is the ability of a body to do work." Anddue_to_its_height.%22">"Gravitational potential energy is the ability of a body to do work due to its height."Gravitational potential energy is a type of potential energy.
