Gravitation: The Four Fundamental Forces of Physics #3

What does Newton's law of gravitation state about objects in the universe?

• It only affects objects on Earth.

• It attracts everything with mass to everything else with mass.

• It is only affected by the distance between objects.

• It is a force that pushes objects apart.

What two factors determine the strength of gravitational attraction between objects, according to Newton's law?

• Color and temperature

• Shape and texture

• Mass and distance

• Speed and direction

How did Albert Einstein's Theory of General Relativity describe gravity?

• As a force that only affects very small particles.

• As a property of mass, space, and time that distorts the fabric of the universe.

• As a magnetic force between objects.

• As a force that only works in a vacuum.

What are the theoretical massless particles that are thought to carry the force of gravity called?

• Photons

• Electrons

• Gravitons

• Neutrinos
