gravity and orbits quick check

Answer 1

Gravity is the force that attracts two objects with mass towards each other. It is responsible for keeping objects on the surface of the Earth and for the motion of celestial bodies in space.

An orbit is the path followed by an object around another object in space due to gravitational attraction. Objects in orbit are constantly falling towards the object they are orbiting, but their forward motion keeps them from crashing into it. The combination of the object's forward velocity and the gravitational pull of the larger object creates a curved orbit.
