**Page 2 - What is Gravity?** 1. **How does mass determine the strength of gravity?** The strength of gravity between two objects is directly proportional to their masses. The more massive an object is, the stronger its gravitational pull. 2. **An orange falls off of a tree. Gravity is pulling the orange in which direction?** Gravity pulls the orange downward, towards the center of the Earth. 3. **Gravity pulls you and everything on Earth towards…** Gravity pulls you and everything on Earth towards the center of the Earth. 4. **The strength of a gravitational pull** **decreases** **as the distance between two objects** **increases**. That’s why you would experience less gravity on top of Mount Everest than you do at sea level. --- **Page 3 - A model of the solar system shows the sun as a loaf of bread. What size is everything else in this model?** In this model, everything else (like the planets) would be much smaller than the loaf of bread representing the sun, often depicted as tiny dots or even smaller objects, illustrating the vast difference in size between the sun and the planets. 1. **Why do objects orbit the sun?** Objects orbit the sun due to the gravitational attraction between the sun and the objects, combined with their initial tangential velocity. This creates a curved path around the sun rather than a straight line. 2. **What prevents the planets in our solar system from floating away?** The gravitational pull of the sun prevents the planets from floating away by keeping them in their orbits. --- **Pages 4-7 are just for your information. Watch the video on Page 7 to review the above content.** --- **Page 8 - In what direction does Earth’s gravity pull objects?** Earth’s gravity pulls objects towards the center of the Earth. 1. **On which two factors does the strength of gravity between two objects depend?** The strength of gravity between two objects depends on their masses and the distance between them.

Why do objects orbit the sun? What prevents the planets in our solar system from floating away?

GPT-4o mini · Answer

1. **Why do objects orbit the sun?** Objects orbit the sun due to the gravitational attraction exerted by the sun. This force pulls the objects toward the sun. However, as these objects move forward with a certain velocity (their tangential velocity), they don't fall directly into the sun. Instead, they follow a curved path, resulting in an orbit. The balance between the forward motion and the gravitational pull creates a stable orbit. 2. **What prevents the planets in our solar system from floating away?** The gravitational force of the sun prevents the planets in our solar system from floating away. This gravitational pull keeps the planets in their elliptical orbits around the sun, counteracting their natural tendency to move in a straight line due to inertia.
