Lesson 1: Gravitational Fields
Hook:
Showing a video of Felix Baumgartner freefalling from the stratosphere displays great visuals of the curvature of the earth and how quickly Felix accelerates due to gravity.
Action:
Afterwards, discuss gravity and acceleration due to gravity and make correlations to the previous use of acceleration due to gravity in earlier units.
Introduce Newton's Law of Universal Gravitation. Discuss what a gravitational field is. Show how gravitational field line patterns differ near Earth and far from Earth. Debrief:
