What else can I help you with?
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?
pattern
What is the rotational symmetry and order of a star?
Since stars are normally spherical objects, they have rotational symmetry of infinite order.
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 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 does gravitational potential energy need in order to be present?
Gravitational potential energy requires an object to have a certain height above a reference point, such as the ground. The potential energy is stored in an object due to its position in a gravitational field. This energy can be released when the object falls or moves downwards.
6 Put the following objects in order of increasing gravitational potential energies?
They all have the same gravitational potential energies.
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
Which property must be the same in order to stop the transfer of energy between two objects?
The temperature of the two objects must be the same in order to stop the transfer of energy between them. Energy will transfer as long as there is a temperature difference between the objects.
How much energy is required to raise a mass of 200kg to a height of 4 m?
Potential energy of the mass referred to the floor level = M g H .At 4 m above the floor, its potential energy will be M g H = (200) (9.8) (4) = 7,840 joules.That's the energy you have to come up with from somewhere in order to hoist the block.
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).
A 40 kg child is in a swing that is attached to ropes 1.7 m long find the gravitational potential energy when the ropes make a 34 degree angle?
The gravitational potential energy of the child can be calculated as PE = mgh, where m is the mass (40 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the vertical height. In this case, the height can be found using h = L(1 - cosθ), where L is the rope length (1.7 m) and θ is the angle (34 degrees). Plugging in the values gives us the gravitational potential energy.
What scientific equipment do you need in order to calculate potential energy?
To calculate potential energy, you primarily need a mass measurement device (like a scale) to determine the mass of an object, and a height measurement tool (like a ruler or tape measure) to determine the height at which the object is located. With these measurements, you can use the formula for gravitational potential energy, PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.
What holds all the planets in order?
Gravitational force is what holds all the planets in their orbits around the sun. This force is determined by the mass of the objects and the distance between them. The gravitational pull of the sun keeps the planets in their respective orbits.
