If an object increases mass with acceleration due to the energy driving force converting to mass then is it true also when there is no driving force but gravitational tug acting to accelerate the object?
Could you be thinking about the Pound and Rebka Mossbauer Effect experiment at Harvard in which photons from an iron-57 source falling from the roof to the basement of the phyics building gained a measurable amount of energy? In this case there was no mass gained, but the photon energy gain was due to gravity.tanzanos said:If an object increases mass with acceleration due to the energy driving force converting to mass then is it true also when there is no driving force but gravitational tug acting to accelerate the object?
So gravitational tug causes an object to gain energy but that energy does not convert to mass? What happens to this energy?Bob S said:Could you be thinking about the Pound and Rebka Mossbauer Effect experiment at Harvard in which photons from an iron-57 source falling from the roof to the basement of the phyics building gained a measurable amount of energy?

For photons, E2=(pc)2 + (m0c2)2, so for photons with zero rest mass, the energy increase is equal to the momentum increase; E = pc.tanzanos said:So gravitational tug causes an object to gain energy but that energy does not convert to mass? What happens to this energy?
Acceleration is the rate of change of an object's velocity over time. It is a vector quantity, meaning it has both magnitude and direction. It is typically measured in meters per second squared (m/s^2).
According to Newton's Second Law of Motion, acceleration is directly proportional to the net force acting on an object and inversely proportional to the mass of the object. This means that the greater the mass, the greater the force needed to accelerate the object.
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. Mass is typically measured in kilograms (kg), while weight is measured in newtons (N).
Gravitational tug, or gravitational force, is the force of attraction between two objects due to their masses. The strength of this force depends on the masses of the objects and the distance between them. The greater the mass of the objects, the stronger the gravitational tug between them.
The mass of an object does not directly affect its acceleration due to gravity. According to the Universal Law of Gravitation, the acceleration due to gravity is the same for all objects, regardless of their mass. However, a larger mass will experience a greater force of gravity, which can affect its overall motion.
