Kepler's 2nd Law

Front

What is Kepler's 2nd Law?

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.

When is the Earth moving the fastest in its orbit?

Back

The Earth is moving the fastest in its orbit in January.

Front

What does the area between points A, B and the Sun represent?

Back

The area represents the space swept out by the planet as it moves from point A to point B.

Front

What is true about the areas swept out by a planet in equal time intervals?

Back

The areas are equal in size, regardless of the planet's position in its orbit.

Front

From which position does a planet appear to move the fastest?

Back

A planet appears to move the fastest from Position A to B.

Front

What is eccentricity in the context of orbits?

Back

Eccentricity is a measurement of how elliptical an orbit is.

Front

How does increasing the distance between an ellipse’s foci affect its shape?

Back

Increasing the distance between an ellipse’s foci increases its eccentricity.

Front

What is the shape of a circular orbit in terms of eccentricity?

Back

A circular orbit has an eccentricity of 0.

Front

What happens to a planet's speed as it gets closer to the Sun?

Back

A planet moves faster as it gets closer to the Sun due to gravitational pull.

Front

What is the relationship between a planet's distance from the Sun and its orbital speed?

Back

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