What is gravity? Explain
a
A force of attraction or repulsion based on the magnetic polarity between two objects
b
A force between molecules that converts kinetic energy to heat energy
c
A force of attraction or repulsion based upon the electric charge between two objects
d
A force of attraction between all objects in the universe that have mass
d
Gravity is a force of attraction between all objects in the universe that have mass. It is responsible for pulling objects towards each other. The strength of gravity depends on the mass of the objects and the distance between them. The larger the mass and the closer the distance, the stronger the gravitational force. Gravity is what keeps planets in orbit around the sun, holds us down to the Earth, and determines the motion of celestial bodies. It is a fundamental force in the universe.
