Question

which remains the same as the distance of an object from earth changes?
size of the force
strength of gravity
mass of the object
weight of the object

Explanation:

• The size of the force (gravitational force) between Earth and an object changes with distance according to the formula \(F = G\frac{Mm}{r^{2}}\) (where \(G\) is the gravitational constant, \(M\) is Earth's mass, \(m\) is the object's mass, and \(r\) is the distance between them).
• The strength of gravity (\(g=\frac{GM}{r^{2}}\)) also changes with distance \(r\) from Earth.
• The weight of an object (\(W = mg\)) changes because \(g\) changes with distance.
• Mass is an intrinsic property of an object and does not depend on its distance from Earth.

Answer:

mass of the object
