Study Notes
Earth and Sun Orbit Mechanics
- Earth orbits the Sun in a counterclockwise direction.
- The orbit occurs at a constant speed, maintaining a stable distance from the Sun.
Moon and Earth Relationship
- The moon orbits the Earth similarly to how the Earth orbits the Sun.
- This orbit also occurs at a constant speed, showcasing a stable gravitational relationship.
Common Characteristics of Orbits
- Both Earth and moon travel counterclockwise during their orbits.
- Motion involves a constant speed, indicating a balance of gravitational forces.
Importance of Gravity
- Gravity prevents Earth from drifting away from the Sun, ensuring the stability of its orbit.
- Absence of gravity would result in a frigid environment, with potential consequences such as floating away and suffocation.
Gravitational Influence Between Earth and Sun
- The gravitational pull of the moon has a more significant effect on Earth compared to Earth’s pull on the Sun.
- Proximity and mass are factors; Earth and moon are closer in distance and mass than Earth and Sun.
Gravity Force Dynamics
- The gravitational force increases when two objects (like a star and a planet) are brought closer together.
- Conversely, when two objects are pulled apart, the gravitational force decreases.
