Inertia
What is force that keeps planets moving in a curved path around the sun called.

Explain how an orbit forms.
An orbit forms when an object moves at a precise speed while gravity pulls it toward a central body, creating an on-going curved path.
What 2 things affects gravity between objects?
Mass and distance.
What is centripetal force?
The force that keeps planets moving in a curved path around the sun.
