Kepler's Law

How can Kepler's laws of planetary motion be applied to analyze the motion of celestial bodies?

• A The closer the eccentricity is to 0, the closer the orbit is to a perfect circle.

• The two points inside the ellipse that determine its shape.

  By observing how quickly a planet moves in different parts of its orbit.

• By understanding that all planetary orbits are shaped like ellipses, not perfect circles.

• By observing the shape and size of their orbits, as well as the time it takes to complete one orbit.

How can the orbital period be calculated using Kepler's laws?

• By measuring the average distance from the sun and using the law of harmonies formula: T^2 = k * r^3.

• By using the relationship between a planet's orbital period and its average distance from the sun to calculate orbital parameters.

• By understanding that all planetary orbits are shaped like ellipses, not perfect circles.

• The two points inside the ellipse that determine its shape.

How can the law of equal areas be used to analyze the motion of celestial bodies?

• By observing how quickly a planet moves in different parts of its orbit.

• The square of a planet's orbital period is directly proportional to the cube of its average distance from the sun.

• By observing the shape and size of their orbits, as well as the time it takes to complete one orbit.

How can the law of ellipses be used to analyze the motion of celestial bodies?

• By measuring the distance between the two farthest points and the two closest points on the orbit.

• It measures how elongated an elliptical orbit is.

• By understanding that all planetary orbits are shaped like ellipses, not perfect circles.

• Planetary orbits are shaped like ellipses, with the sun located at one of the two foci.
