Question

select all the correct answers. according to newtons law of universal gravitation, which statements are true? as we move faster, the force of gravity on us increases. as we gain mass, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we move to higher altitudes, the force of gravity on us decreases.

Explanation:

Newton's law of universal gravitation is $F = G\frac{Mm}{r^{2}}$, where $F$ is the gravitational - force, $G$ is the gravitational constant, $M$ and $m$ are the masses of two objects, and $r$ is the distance between their centers of mass. As mass $m$ (our mass) increases, the gravitational force $F$ on us increases. As we move to higher altitudes, $r$ increases, and the gravitational force $F$ on us decreases. The speed of movement has no direct relation to the gravitational force according to this law.

Answer:

As we gain mass, the force of gravity on us increases.
As we move to higher altitudes, the force of gravity on us decreases.
