what is the relationship between gravitational potential energy and kinetic energy?
166883
When an object falls, its gravitational potential energy is changed to kinetic energy. You can use this relationship to calculate the speed of the object's descent. Gravitational potential energy for a mass m at height h near the surface of the Earth is mgh more than the potential energy would be at height 0.

Gravitational potential energy is energy in an object that is held in a vertical position, due to the force of gravity working to pull it down. ... Gravitational potential energy increases as weight and height increases. Potential energy is energy that is stored in an object or substance.

Potential energy is energy an object has because of its position relative to some other object. ... Notice that gravitational potential energy has the same units as kinetic energy, kg m2 / s2. In fact, all energy has the same units, kg m2 / s2, and is measured using the unit Joule (J).

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

Potential energy is stored energy -- it has the potential to do work! Kinetic energy is the energy of motion!

Potential Energy is the energy stored in a system when work is done on it by some external agency. Potential is just the work done per unit something of that system e.g. electric potential is just work done per unit charge. Similarly,gravitational potential is work done per unit mass.

If an object, such as a ball is lifted above the ground it has gravitational potential energy. If the ball is then dropped from rest it will fall back to the ground. The gravitational potential energy is converted to kinetic energy .

The sum of an object's potential and kinetic energies is called the object's mechanical energy. As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

Kinetic energy, form of energy that an object or a particle has by reason of its motion. ... Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.

Energy can be divided into two groups: kinetic and potential. Kinetic energy is the energy of motion. All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward.

A ball held in the air, for example, has gravitational potential energy. If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.

The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space.

what is the relationship of molecular energy motion and kinetic energy? the relationship between molecular motion and kinetic energy is that the faster the molcules are moving, the higher the kinetic energy is.

Gravitational Potential Energy. Definition: Gravitational Potential Energy ( PEg ) is given by: PEg = mgy, (3) where m is the mass of an object, g is the acceleration due to gravity, and y is the distance the object is above some reference level.

Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object.

Potential energy is energy that is stored in an object or substance. Gravitational potential energy is energy in an object that is held in a vertical position. Elastic potential energy is energy stored in objects that can be stretched or compressed.

Potential energy is not relative to the environment of an object. Kinetic energy can be transferred from one moving object to another, say, in collisions. Potential energy cannot be transferred. Flowing water, such as when falling from a waterfall.
