What is the relationship between mass height and gravitational potential energy?
The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
Is gravitational potential energy affected by mass?
The mass of the object- The more mass an object has, the more gravitational potential energy it will have if it is given a position with the potential to fall. The distance it is from the surface of the Earth- The farther an object can fall, the more gravitational potential energy it will have.
What does the gravitational potential energy depend on?
Gravitational potential energy depends upon the mass and height of the body.
Does the gravitational force change with mass?
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
How does doubling the mass affect gravitational potential energy?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
Does an object with less mass have more potential energy?
Objects that have more mass have more potential energy. Similarly, objects that have less mass have less potential energy.
What two things does gravitational potential depend on?
Gravitational potential energy depends on several things: it depends on the mass of the object, the gravitational acceleration of the object due to the earth as well as the displacement of the object from the ground.
How does mass and speed affect potential energy?
As the velocity increases, the electron will gain more kinetic energy, and its potential energy decreases. But the system's total energy remains the same because the gain of kinetic energy compensates for the loss of potential energy.

How does gravitational potential energy change?
If we release the mass, gravitational force will do an amount of work equal to on it, thereby increasing its kinetic energy by that same amount (by the work-energy theorem). We will find it more useful to consider just the conversion of to without explicitly considering the intermediate step of work. (See Example 2 .) This shortcut makes it is easier to solve problems using energy (if possible) rather than explicitly using forces.
What is the unit of gravitational potential energy?
Note that the units of gravitational potential energy turn out to be joules, the same as for work and other forms of energy. As the clock runs, the mass is lowered. We can think of the mass as gradually giving up its 4.90 J of gravitational potential energy, without directly considering the force of gravity that does the work.
How does a roller coaster lose potential energy?
The roller coaster loses potential energy as it goes downhill. We neglect friction, so that the remaining force exerted by the track is the normal force, which is perpendicular to the direction of motion and does no work. The net work on the roller coaster is then done by gravity alone. The loss of gravitational potential energy from moving downward through a distance equals the gain in kinetic energy. This can be written in equation form as Using the equations for and we can solve for the final speed which is the desired quantity.
What is the final kinetic energy?
This means that the final kinetic energy is the sum of the initial kinetic energy and the gravitational potential energy. Mass again cancels, and
What is the ratio of gravitational potential energy in the lake to the energy stored in the bomb?
(b) The ratio of gravitational potential energy in the lake to the energy stored in the bomb is 0.52. That is, the energy stored in the lake is approximately half that in a 9-megaton fusion bomb.
What happens to the energy of an object as it descends without friction?
As an object descends without friction, its gravitational potential energy changes into kinetic energy corresponding to increasing speed, so that
What is work done against gravity in lifting an object?
Work done against gravity in lifting an object becomes potential energy of the object-Earth system.
