What is the force that keeps the Earth and other planets in their orbital paths?

Gravity

Explanation:

Gravity is a force that pulls the surface of the earth and keeps the planets in orbits around the sun.

First, gravity is the force that pulls us to the surface of the Earth, keeps the planets in orbit around the Sun and causes the formation of planets, stars and galaxies.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

c) up is the direction the magnetic force is acting on the charge.
