Gravity

Gravity Explained Simply Watch the video below and answer the questions that follow it Mass and Distance What is Gravity? Circle all that apply The bending of space and time What keeps us from falling off the Earth What keeps the Earth in orbit around the sun What caused the sun, planets, and moons to form True or false? As the distance between two objects increases the force of gravity decreases True False True or false? If the mass of an object decreases the force of gravity it exerts increases True False How To Think About Gravity Watch the video and answer the questions below 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. What Causes Tides? Watch the video and check out this link on tides to be able to answer the question below Complete the sentence by adding the correct words in the blanks The moon's gravitational pull generates something called the tidal force. On the side of Earth that is directly facing the moon, the moon's gravitational pull is the strongest. The water on that side is pulled strongly in the direction of the moon.
