MTSS Pre-Assessment (Planetary Motion and Kepler's Laws)

Slow, circular movement at the top of Earth's axis

• precession
• barycenter
• revolution

When the moon revolves around the Earth, the Earth wobbles a little because the moon's gravity is tugging on it.

• Nutation
• Precession
• Barycenter
• Revolution

A wobble back and forth

• Rotation
• Nutation
• Revolution

The center of mass of an object

• Angle of Insolation
• Barycenter
• Equinox

Earth's orbit follows an elliptical path.

• Kepler's 1st law
• Kepler's 2nd law
• Kepler's 3rd law
• Nutation

When Earth orbits around the sun, it slows down when it is close to the sun. It speeds up its orbit when it is further from the sun. This is because the sun's gravity is stronger when you are closer to it.
