When calculating gravitational potential energy you must use?
the distance between the object and the center of the Earth
What is gravitational potiential energy?
Potential energy is energy done to place something somewhere, against a force (not any force, it must be a so-called "conservative force", but I am only mentioning this for completeness sake). Specifically, gravitational potential energy is the energy an object has when it is raised above ground level. You need to supply energy (as work) to lift it up; in theory, this energy can be recovered if the object falls down.
Which factors must be known to calculate an ovjects gravitational potential energy?
Just look at the formula, the factors are all there. GPE = mgh (mass x gravity x height)
What condition must be met in order for the formula for calculating the probability that and event E occurs?
The event E must be well defined.
How does one go about calculating an annuity payment?
One goes about calculating an annuity payment in a number of ways. First, one must determine the type of annuity. Second, one must find the option for payout. Then, one must determine the other details about the annuity and finally, factor in how the payment will be working in relation to the time frame of payment.

What factors must be known to calculate an object gravitational potential energy?
its mass and height
Which factors must be know to calculate an object gravitational potential energy?
Mass speed
What must you do first before determining gravitational PE?
Before determining gravitational potential energy, you must identify the object's height or distance above a reference point, like the ground or a particular level. This reference point will help calculate the gravitational potential energy based on their relative positions.
Which factors must be known to calculate an object's gravitational potential energy?
To calculate an object's gravitational potential energy, you need to know the object's mass, the acceleration due to gravity, and the height at which the object is located above a reference point. The formula for gravitational potential energy is 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.
How can it be explained that gravitational potential is negative?
It all depends what energy level is arbitrarily assigned a value of zero. In gravitational potential energy, it is common to assign a value of zero to the potential energy when objects are infinitely far away from each other; in this case, if they are closer together, they must needs have a negative energy. But if another definition is used, the numbers will vary.

Why do roller coasters end lower than where they start?
Since the top of the first hill is the highest point on the track, it's also the point at which the roller coaster's gravitational potential energy is greatest. As the roller coaster passes over the top of the first hill, its total energy is greatest. Most of that total energy is gravitational potential energy but a small amount is kinetic energy, the energy of motion. From that point on, the roller coaster does two things with its energy. First, it begins to transform that energy from one form to another--from gravitational potential energy to kinetic energy and from kinetic energy to gravitational potential energy, back and forth. Second, it begins to transfer some of its energy to its environment, mostly in the form of heat and sound. Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic energy increases. Each time the roller coaster goes uphill, its kinetic energy decreases and its gravitational potential energy increases. But each transfer of energy isn't complete because some of the energy is lost to heat and sound. Because of this lost energy, the roller coaster can't return to its original height after coasting downhill. That's why each successive hill must be lower than the previous hill. Eventually the roller coaster has lost so much of its original total energy that the ride must end. With so little total energy left, the roller coaster can't have much gravitational potential energy and must be much lower than the top of the first hill.
What is the gravitational potential energy of a chalk lying on the floor?
The gravitational potential energy of an object is given by the formula U = mgh, where m is the mass of the object, g is the acceleration due to gravity (approximately 9.81 m/s^2), and h is the height of the object above the reference point. Since the chalk is lying on the floor, its height above the reference point is zero, so its gravitational potential energy is also zero.

What is the initial velocity that must be given to a 1kg mass if it is to move to a height of 20m. what is the total energy?
The initial velocity needed can be calculated using the conservation of energy principle. The gravitational potential energy at height 20m is equal to the initial kinetic energy given to the mass. Using the equation for gravitational potential energy (mgh), where m = mass, g = acceleration due to gravity (9.81 m/sĀ²), and h = height (20m), we can calculate the initial velocity. The total energy of the system will be the sum of the initial kinetic energy and the potential energy at height 20m.
Can an object have no either potential energy and kinetic energy?
Yes. Potential energy is energy that has not yet been released. Kinetic energy is energy or an object already in motion.Think of a ball 1 mile up in the air that begins to fall. After it has fallen 10 feet, releasing some, but not all of its potential energy, it has built up some kenetic energy as well from the motion of falling 10 feet, but still has 5270 feet worth of potential energy to go. What happens as the ball falls is that it gradually changes all of its potential energy into kinetic energy.co
