Describe the effect that height has on the force and energy needed to lift an object?
The force needed to lift an object is directly proportional to its weight, not its height. However, lifting an object at a greater height requires more energy due to the work done against gravity over a longer distance. So, height affects the energy required to lift an object but not the force needed.
How can doing work on a object increase its potential energy?
When work is done on an object by applying a force over a distance, the object gains potential energy. For example, lifting an object against gravity increases its height and potential energy due to the work done in lifting it. This increase in potential energy is a result of the energy transferred to the object from the external force applied to it.
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
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
Work done in lifting and lowering an object?
The work done in lifting an object is positive, as energy is input to move it against gravity. The work done in lowering an object is negative, as the object is moving in the direction of the force of gravity, and energy is being released. Overall, the work done will depend on the distance the object is lifted or lowered and the force applied.

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
What are the variables on which the gravitational potential energy of an object depends on?
The gravitational potential energy of an object depends on its mass, the acceleration due to gravity, and its height above a reference point. This energy is a measure of the work done in lifting an object against gravity to its current position.
How does an incline plane affect the work that is done on an object?
it reduces the work by making an object easier to carry or lift to a higher or lower ground
If you lift 1600 meters straight up how much work did you do?
To calculate the work done when lifting an object, you can use the formula: work = force × distance. The force required to lift an object is equal to its weight, which is mass × gravity. So, you would need to know the mass of the object to calculate the work done when lifting it 1600 meters.
What is gravitationla potential energy?
Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. The potential energy is based on the object's height above a reference point and is related to the work done in lifting or lowering the object in the gravitational field. The higher an object is lifted, the greater its gravitational potential energy.
What happens when work is done on a object?
When work is done on an object, it gains energy in the form of kinetic energy or potential energy depending on the type of work done. The object's speed, height, or deformation may change as a result of the work done on it.
The work done in lifting 30 kg of bricks to a height of 20 m on a building under construction is?
The work done in lifting 30 kg of bricks to a height of 20 m would be ( W = mgh = 30 kg \times 9.8 m/s^2 \times 20 m = 5880 , \text{Joules} ). The work done is 5880 Joules.
