Gravity

Learn about gravity and its effects with our engaging worksheet! Understand attraction, mass, and space.

When you drop a rock from a cliff, which of the following happens? Only the rock falls to the Earth Only the Earth falls up to meet the rock The rock and the Earth fall towards each other None of the above If you place two teenagers with equal mass in space: They will fall towards each other They will remain in place They will move apart We cannot even make an educated guess about what will happen What is gravity? What goes up must come down Everything is attracted to everything else Only small things are attracted to larger things Only larger things are attracted to smaller things Why do astronauts weigh less on the moon than they do on the earth? It's a little known fact, but space suits generally make people weigh less. The moon has less mass than the Earth. Therefore, it has a smaller gravitational pull on the astronaut. The Earth is closer to the sun. Astronauts weigh the same no matter where they are. What causes gravity? The force of magnetism. The amount of electrons in a particular object. We don't know, conclusively. Scientist determine the amount that objects are attracted to one another.
