3. Read “Going Ballistic” Answer the following questions: ▫Research: What is air resistance? What affects that amount of air resistance on an object? ▫What is the shape of most orbits? ▫Draw a rough sketch of the “hole to China” indicating where an individual who falls into this hole is at rest and at maximum speed. ▫What is free fall? How is the International Space Station and the moon in free fall? Write a paragraph to explain it to a 5 year old. ▫Why do you feel weightless in free fall?

4. What is acceleration due to gravity? Get out the Probe!!!

5. On Earth, Acceleration due to gravity - “little g” a g or g = 9.81m/s 2 [ towards centre of Earth ] or [  ] ▫This varies depending on the Earth’s radius at a given point but this is a generally accepted average ▫It’s CONSTANT acceleration! For our calculations, ▫We assume no air resistance
