Rockets and Satellites

2. Rockets
What makes an object move in a circle?

3. The object moves in a circle, therefore it is constantly accelerating

4. What causes the acceleration is the pulling force, like the tension of a string

5. How do rockets lift off?
They lift off into space by using Newton’s 3rd Law of motion

6. A rocket can rise into the air because the gases it expels with a downward action force exert an equal but opposite reaction force on the rocket

7. Satellite Is any object that orbits another object in space
Can be natural or man-made

8. Circular Motion
An object traveling in a circle is accelerating because it is constantly changing directions

9. Any force that causes an object to move in a circular path is a centripetal force
