Questions and Answers
What is Kepler's First Law?
What is Kepler's First Law?
- The planets orbit in an elliptical shape. (correct)
- The sun is at the center of the planet's orbit.
- A planet's orbit is not affected by the sun's mass.
- The planets orbit in a circular shape.
What does Kepler's Second Law state about a planet's orbit?
What does Kepler's Second Law state about a planet's orbit?
A planet spends equal amount of time in its orbit at perihelion & aphelion.
What does Kepler's Third Law relate?
What does Kepler's Third Law relate?
The time it takes a planet to orbit the sun is related to its distance from the sun.
Study Notes
Kepler's First Law
- Planets move in elliptical orbits with the Sun situated at one focus of the ellipse.
- The second focus of the ellipse is irrelevant due to the Sun's significant mass and gravitational influence on the planets.
Kepler's Second Law
- A planet sweeps out equal areas in equal times during its orbit around the Sun.
- This implies that a planet travels faster when it is closer to the Sun (perihelion) and slower when it is farther away (aphelion).
Kepler's Third Law
- The time taken for a planet to complete one orbit around the Sun is proportional to the average distance between the planet and the Sun.
- This law illustrates a relationship akin to that of runners on a track, where the orbital period increases with the distance from the Sun.
