Your mass remains the same.
you increase or decrease mass by taking the mass out
If you increase the mass of the Earth and decrease the mass of the Sun, the gravitational pull between the Earth and the Sun would change. This could potentially alter the orbits of the planets in our solar system and have significant effects on the stability and dynamics of the entire system.
The two main factors that affect density are the mass of an object and its volume. An increase in mass or a decrease in volume will lead to an increase in density, whereas a decrease in mass or an increase in volume will result in a decrease in density.
The mass of the Earth remains relatively constant because the amount of matter on Earth does not significantly increase or decrease. However, the Earth gains a small amount of mass each year from meteorites and space dust that enter the atmosphere.
The only way to change anythings gravity is to change its' mass. (apex) Increase the mass of the object Decrease the distance of the object from Earth
You either Decrease mass or increase spring force.
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
A decrease in mass of a system will increase the natural frequency of the system. This is because the natural frequency of a system is inversely proportional to the square root of the mass. So, as mass decreases, the natural frequency will increase.
More mass --> more gravity.
The length of the day would decrease because of conservation of momentum principle - Earth would rotate faster when shrinked.
The FORCE, or Gravitational Pull of the Earth on an Object is DIRECTLY PROPORTIONAL to the Object's Mass. Force = Mass x Acceleration of Gravity So, if Mass goes up, Pull goes up, If the Mass goes down, the Pull goes down.
For Newtonian gravity, observe that the force (F) between two bodies is a function of only the mass of the bodies and distance between the center of mass of those bodies. F = (G*m1*m2)/r^2; where, G = Gravitational constant, m1 = mass of one body, m2 = mass of second body, r = distance between bodies. It is directly proportional to the mass of the bodies and inversely proportional to the square of the distance between them. Thus, the methods of increasing the magnitude of the force are to increase the mass of either or both of the bodies or decrease the distance between the bodies. Reducing the force can be accomplished by doing the opposite: decreasing mass or increasing distance.
