Question

What force pulls planets into a curved path when they are orbiting the sun?

Gravity
Acceleration
Centripetal force
Mass

Answer 1

The force that pulls planets into a curved path when they are orbiting the Sun is **gravity**. Gravity is the attractive force between two masses, and it is what keeps the planets in orbit around the Sun. While centripetal force is a concept that can be used to describe the necessary force to keep an object moving in a circular path, in the case of planetary motion, it is the gravitational force that acts as the centripetal force. So, in this context, **gravity** is the most accurate answer.
