Study Notes
Chapter 5: Gravity
- Special relativity describes the relationship between energy and mass using the equation E = mc².
- Newton's Third Law states that forces always occur in pairs acting in opposite directions.
- Aristotle incorrectly believed that objects fall at a constant rate of speed.
- Observations of stars during eclipses support Einstein's general theory of relativity.
- Gravity exists in space.
- Objects in orbit revolve around a common center of mass.
- Changing the direction of a moving object changes its velocity.
- Universal gravitation describes the attraction between all objects with mass.
