What causes all of the planets in the solar system to orbit around the Sun?

• the Sun's magnetic field pulls on all of the planets due to the metal core of each planet

• the massive size and mass of the Sun creates an extremely strong gravitation force that holds all planets in orbit

• the planets orbit the Sun due to its very fast rotational speed causing the graviton effect

• none of these

What is the "Goldilocks Zone"?

• The warm zone located around a planet that provides a blanket like effect

• The zone that life has a hard time existing and will likely never exist

• The habitable zone around a star where the temperature is just right to support life.

• none of these

A basketball and a volleyball are roughly the same size but have different mass. In Science class, students conducted an experiment of what would happen if both were dropped from the roof of the school. What do you think the students saw?

• both balls hit the ground at the same time due to the force of gravity being equal on both balls

• the basketball hit slightly before the volleyball because it has a little more mass than the volleyball

• the volleyball hit first because it is lighter and therefore accelerates faster than the basketball with more mass

• none of these

• slingshot effect

• shotgun effect

• none of these

The gravity on the outer planets of our solar system is not as strong as the inner planets. Why is this?

• the inner planets are smaller and therefore have less gravity than the larger outer planets

• gravity is the same on all planets in the solar system regardless of their size and distance from the Sun

• none of these

• the outer planets are further away and therefore gravity is weaker than on the inner planets

True or False? The closer an object is to another the stronger the gravitational force.

• True

• False

• Not enough information to answer the question
