  1. Acceleration Due to Gravity

  2. Eureka – Acceleration P.2 • https://www.youtube.com/watch?v=ESQKTdNGpzw • Eureka – Gravity • https://www.youtube.com/watch?v=pnhAWFS5vLU

  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” • ag or g = 9.81m/s2 [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

  6. How fast does it hit the ground? • https://www.khanacademy.org/science/physics/one-dimensional-motion/kinematic_formulas/v/impact-velocity-from-given-height
