=V. Orbiting Satellites= =A. Rocket can rise into the air because the gases it expels with a downward force exert an equal but opposite force on a rocket= =1. Upward pushing force= thrust= =i. Thrust greater than the downward pull of gravity, there is a net force in upward direction= =ii. Rocket accelerates upward= =B. Satellite= =1. Any object that travels around another in space= =2. Circular Motion= =i. artificial satellites travel in circular path around Earth= =3. Centripetal Force= =i. center -seeking= =ii. Any force that causes an object to move in a circle= =iii. Satellite- c-force is the gravitational force that pulls the satellite towards the center of Earth= =4. Satellites do not travel straight up in the air, they move around the Earth= =5. Satellites in orbit around Earth continually fall toward Earth, but because Earth is curved they travel around it= =6. Higher orbit, satellites move more slowly and take longer to circle Earth= =__Quiz__= =1. Newton's third law of motion- every time there is a force on an object, the object will exert an equal and opposite force= =2. Draw arrow from satellite pointing to Earth= =3. Any object moving around another object in space= =4. Gravity - it would no longer orbit Earth, it would move in a straight line= =__Study Guide__= =25. False- Gravity= =28. Satellite= = =
