Question

what two factors affect the strength of gravity?
mass and weight
weight and distance
mass and distance
rewatch

Explanation:

According to Newton's law of universal gravitation \(F = G\frac{m_1m_2}{r^2}\), where \(F\) is the gravitational force, \(G\) is the gravitational constant, \(m_1\) and \(m_2\) are the masses of two objects, and \(r\) is the distance between their centers of mass. The strength of gravity (gravitational force) depends on the masses of the objects (\(m_1\) and \(m_2\)) and the distance (\(r\)) between them. Weight is the force of gravity acting on an object (\(W=mg\), where \(m\) is mass and \(g\) is the acceleration due to gravity), so it is a result of gravity, not a factor affecting the strength of gravity.

Answer:

mass and distance
