Work done in lifting and lowering an object?
potential energy
What is The work done holding a 50 kg object at a height of 2 m above the floor for 10 seconds?
The answer is 0. If you used the formula of =>mgh, you would get a value which would be wrong. The question is a trick question. There is no work done in 'holding' an object but work would be done in 'lifting' an object. Hence, 0. ~Dartz
What is the relationship between work and gravitational potential energy?
Work = energy (by the Work-Energy Equivalence Theorem).The work done in lifting an object shows up as the gravitational potential energy of the object: W = mgh, where W is the work done; m is the object's mass; g is the acceleration due to Earth's gravity; and h is the height to which the object is lifted. (This assumes that the lifting is done near Earth's surface, with gravity effectively constant.)ALL Credit goes to Argent at yahoo answers
How much work is done when an object is thrown upward?
mass of the object (times) gravitational acceleration (times) height the object reaches.
How much work is done in lifting a 20 kg object through a distance of 0.40 m Use g 10 ms?
Work Done= Force X Distance moved by the object in the direction of the force = 20kg X 10N/kg X 0.40m = 80J

How do you calculate the work done if a boy lifts a body of 50kg to a height of 20m?
work done = m*g*h = mass * acceleration due to gravity * height change. work done = 50 * 9.8 * 20 work done = 9 800 joules
How much work is done when an object is thrown upward?
mass of the object (times) gravitational acceleration (times) height the object reaches.
How much work is done by gravity as the riders are lifted to a height of 60 meters?
Gravity does not lift. The force is doing the work by lifting the riders. When the riders come down from the 60 meter height, then gravity will be at work.
How much work is done in lifting a 20 kg object through a distance of 0.40 m Use g 10 ms?
Work Done= Force X Distance moved by the object in the direction of the force = 20kg X 10N/kg X 0.40m = 80J
When we carry an object across a room without lifting it or setting it down we do no physical work on it?
That's correct. For work to be done, the force must have a component in the direction of the movement.
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....
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.
What is the process scientist use to find the volume of an irregular object?
Displacement is the process used to find the volume of an irregular object. This is done by submerging the object in water and measuring either the height the water rises or the volume of water that overflows the container.
Energy of an object increases when what is done on the object?
When force is done on the object
