Keplers Laws

Front

What does Kepler's 2nd Law state?

Back

Kepler's 2nd Law states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time, meaning a planet moves faster when it is closer to the Sun.

What is the eccentricity of a circle?

Back

The eccentricity of a circle is zero.

What are the two fixed points in an ellipse called?

Back

The two fixed points in an ellipse are called foci.

What is the maximum eccentricity of an ellipse before it becomes a line?

Back

The maximum eccentricity of an ellipse before it becomes a line is .99.

What is the definition of eccentricity in relation to an ellipse?

Back

Eccentricity is a measure of how much an ellipse deviates from being circular, ranging from 0 (circle) to 1 (line).

Front

What is the significance of the foci in an ellipse?

Back

The foci are significant because they determine the shape of the ellipse and the gravitational forces acting on the orbiting body.

How does the distance from the Sun affect a planet's orbital speed?

Back

The closer a planet is to the Sun, the faster it moves in its orbit due to the stronger gravitational pull.

What is the relationship between the area swept out by a planet and time according to Kepler's 2nd Law?

Back

The area swept out by a planet in its orbit is proportional to the time taken, meaning equal areas are covered in equal times.
