===Notes for teachers===
''These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.''

Forces can act at a distance and are called non-contact forces. To understand gravitation, we need to understand inertial and gravitational properties of mass. Gravity is one of the four fundamental forces. This document further discusses the concept of acceleration due to gravity and gravitational potential energy. Gravity is responsible for planetary motion and introduces the Kepler's laws of planetary motion.

These are some of the questions we will explore here.
#Gravitational force acts over a distance through a field and is one of the four fundamental forces. Gravitational force is a very small force. Idea of a force field and that forces can act at a distance. The distance over which the effect of a force can be felt is called its field. Gravitation explains several phenomena
##the force that allows us to move on Earth
##the motion of the moon around the Earth
##the motion of the planets around the Sun
##the tides due to the moon and the sun
====Concept #1 - Contact and Non-Contact Forces====
===Activities ===
=====Learning objectives=====
