What is the link between the sun's gravity and the motion of a planet?

What is the link between the sun's gravity and the motion of a planet in the solar system.What is the link between the sun's gravity and the motion of a planet?they are perpendicular and equal in force to each otherWhat is the link between the sun's gravity and the motion of a planet?I'm not sure I understand the question, but I'll try. Because we are in orbit around the sun by its gravity, we revolve around it. However, it is inertia that keeps us from being pulled into the sun.
