using your previous answer, why does the force of gravity change in this way? check you answer.

Explanation:

Step1: Recall gravitational force formula

The gravitational force $F = G\frac{Mm}{r^{2}}$, where $G$ is the gravitational - constant, $M$ is the mass of the Sun, $m$ is the mass of the object being affected, and $r$ is the distance between the Sun and the object.

Step2: Analyze distance change

The Earth's orbit around the Sun is elliptical. The distance $r$ between the Earth and the Sun changes over the course of a year. When the Earth is closer to the Sun (perihelion), $r$ is smaller, and according to the formula $F = G\frac{Mm}{r^{2}}$, the gravitational force $F$ is larger. When the Earth is farther from the Sun (aphelion), $r$ is larger, and the gravitational force $F$ is smaller.

Answer:

The force of gravity changes because the distance between the Earth and the Sun changes over the year due to the elliptical orbit of the Earth around the Sun. When the distance is smaller, the gravitational force is larger, and when the distance is larger, the gravitational force is smaller.
