Homework Statement
Where does mass get the force of gravity?
Homework Equations
F = G(m1 x m2)/r^2
F = force (N)
G = Gravitational constant (Nm^2/kg^2)
m = mass
r = distance between m1 and m2
dhayward said:how is the gravitational constant derived?
The force of gravity is directly proportional to the mass of an object. This means that the larger the mass, the stronger the force of gravity.
According to Newton's Law of Universal Gravitation, the force of gravity is determined by the mass of two objects and the distance between them. Objects with more mass have a greater gravitational pull because they have more mass to attract other objects.
The mass of the Earth is what creates the force of gravity that keeps objects on the surface. The greater the mass of the Earth, the stronger the force of gravity on its surface.
Although objects with more mass have a stronger gravitational pull, they also have a greater inertia, meaning they are more resistant to changes in motion. This is why objects with different masses fall at the same rate in a vacuum.
Einstein's theory states that gravity is not a force between masses, but rather the curvature of spacetime caused by the presence of mass. This means that the more massive an object is, the more it warps the fabric of spacetime, resulting in a stronger gravitational pull.
