An attractive force that acts between all matter that has mass, and is proportional to mass.
An attractive force that acts between all matter that has mass, and is proportional to mass. It is in fact a relatively weak force. Only very large objects exert a significant influence due to gravity. Gravity keeps the planets orbiting the Sun, the Moon orbiting the Earth, and keeps us from floating off into space.
