Gravity & the solar system

Instructions Work through the following tasks and use the information to answer the Gravity Main Ideas on your handout. Watch all videos, read articles, and complete any questions and tasks in order.If you need to log out before you are finished, scroll to the bottom and SAVE your work. When you have completed all the tasks, click the TURN IN button for your work to be graded. What is Gravity? Watch the video and answer the questions below. Fill in the blanks with the correct words from the video. For gravity, the size of the pull depends on the mass of the objects. Because of gravity, the planets orbit around the sun and the moon orbits around the earth. Mass and Distance Which object would have a greater gravitational pull? Apple Bowling Ball Ping Pong Ball Your Awesome Science Teacher The Two Forces That Keep the Planets in Motion Around the Sun How do Gravity and Inertia work together to keep our solar system in motion?Read the article in the link and complete the next task. Planets in Motion What are the 2 forces that keep the planets in their orbit? Gravity Magnetism Inertia Electrostatic Air Resistance Friction Select all that apply...The planets move in there orbits because... Inertia makes them want to continue in a straight line The gravity of the sun wants to pull them towards the sun. Inertia and Gravity fight each other to balance out the push and pull of the planets so that one doesn't overpower the other Magnetism within the planets magnetic field counteracts with the iron in the sun causing the like poles to repel each other. Orbits What is an Orbit?Have you ever wondered what could happen in the time it takes Earth to orbit the sun just one time? From the first day of Earth's orbit to its last, you'll celebrate a birthday, move on to the next grade, and maybe even grow a few inches.That's because it takes a full year - or just over 365 days - for Earth to orbit, or revolve, around the sun. An orbit is a repeating path that one object in space takes around another. All orbits are elliptical in shape, meaning they're egg-shaped, or oval, rather than circular. What is the shape that celestial bodies orbit around other celestial bodies? straight line Round Elliptical Random How long does it take the Earth to orbit the Sun completely? 365 days 6 months 30 days A decade The Moon and Ocean Tides What Causes Tides? (click to find out!) Check out the site linked above. Complete the sentence by adding the correct words in the blanks. The moon's gravitationalpull generates something called the tidal force. On the side of Earththat 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.
