Why is gravitational potential near to an isolated mass negative?
Because you have to do work on the pair ... add work to them ...in order to separate them.
What is a grouping of objects where order does not matter?
They are sets of objects.
What is the order that is inherent in a particular set of objects?

If you want to lift a 5kg box to the height of meter how much work must be done?
Did you say one meter ?You'll have to give the box 49 joules of additional gravitational potential energy.But since the human muscular system is not 100% efficient, you'll have to spendsomewhat more energy than that in order to do the job. The additional energythat you put into the effort will show up in the form of elevated body temperature,increased heart rate and blood pressure, and warm perspiration on your brow.
What is the rotational symmetry and order of a star?
Since stars are normally spherical objects, they have rotational symmetry of infinite order.
6 Put the following objects in order of increasing gravitational potential energies?
They all have the same gravitational potential energies.
What does gravitational potential energy need in order to be present?
Look at the formula for gravitational potential energy: PE = mgh. It is the product of mass, gravity, and difference in height. Therefore, those three factors are required.
What type of energy can be potential energy?
Potential energy is the available energy available to an object in order to perform "work". This can take the form of batteries and similar objects, but most frequently, it is used specifically in the context of motion.If you think about a roller coaster, at the top of the hill, it has potential energy. As it begins to descend, it changes to kinetic energy which causes the roller coaster car to accelerate down the hill.Stationary energy is known as potential energyit is the energy of shape and position
What types of energy are attributable to each of the four fundamental forces?
The four forces affecting matter are (in order of increasing strength): 1. Gravitational Force : hydraulic energy or water falls 2. Electromagnetic Force : electricity as secondary energy 3. Weak Nuclear Force: ionizing radiation4. Strong Nuclear Force: nuclear fissionWhenever there is a force, or more precisely a so-called "conservative force", there is an associated potential energy. Each of the fundamental forces have related potential energy; thus, there is gravitational, electrical & magnetical, and nuclear potential energy.I am not entirely sure about the weak force; but I assume it would be lumped together with the strong force, in the category of "nuclear energy".Chemical energy, as well as elastic energy, are also types of potential energy that are related to electrical forces.
How big does an object have to be in order for it to have enough gravity to attract?
All objects with mass have gravitational attraction
Why is gravitational potential near to an isolated mass negative?
Because you have to do work on the pair ... add work to them ...in order to separate them.
What is the relation of gravitational field with conservative systems?
Because in many situations the gravitational field doesn't show any dependence on time (excluding some situations of oscillating fields) it satisfies requirements for a system to be conservative (in order a system to be conservative it's potential energy should not have dependence on time).
Is mechanical energy the energy of movement?
No. Potential energy relates to an objects position on the earth, specifically it's altitude. Mechanical energy is a form of kinetic energy but it can occasionally be considered "work done" in a more general sense
What must you know in order to tell the gravitational force between two objects?
The masses, the distance, and the Law of Universal Gravitation.
What does the energy Hill on an energy diagram represent?
The additional potential energy the reactants must gain in order to react
What does the energy hill represents on an energy diagram?
The additional potential energy the reactants must gain in order to react
What must you know in order to determane the gravitational force between 2 objects?
You need to know . . . -- the mass of each object -- the distance between their centers of mass -- the value of the universal gravitational constant
