Kepler’s 1st Law

Describes how planets, moons, and satellites move in elliptical orbits around larger bodies.

Kepler’s 2nd Law

Explains that a planet moves faster when it is closer to the Sun and slower when farther away.

Kepler’s 3rd Law

Relates the orbital period of a planet (T) to its average distance from the Sun (R) with the equation T² ∝ R³.

Orbital Velocity

Changes with distance from a star; the closer an object is, the faster its orbit.

Newton’s Law of Gravitation

Explains how gravitational force (F) decreases as distance (r) increases.

Hubble’s Law

Used to predict the motion of distant galaxies through the observation of redshift in light.

Newton’s Laws

Describe the acceleration of a planet toward the Sun and how this produces observed orbits.

Earth’s Period of Rotation

The time it takes for Earth to spin once on its axis.

Earth’s Period of Revolution

The time it takes for Earth to orbit once around the Sun.

Earth’s Axial Tilt

The tilt of Earth on its axis affects the seasons in the Northern and Southern hemispheres.

Moon Phases

The different appearances of the moon based on its position relative to Earth and the Sun.

Synchronous Rotation

The reason we always see the same side of the moon; the moon rotates on its axis in the same time it takes to orbit Earth.

Lunar Cycle Duration

The period of time it takes to complete a full cycle of moon phases (e.g., Full Moon to Full Moon).

Apparent Diameter of the Moon

Changes as it orbits Earth, resulting in different types of eclipses: partial and total.

Spring Tides

Occur when the moon is in the new or full phase and produces the highest tides.

Neap Tides

Occur when the moon is in the first or last quarter phase and results in the lowest tides.

Solar Eclipse

Occurs when the moon is positioned between Earth and the Sun, blocking sunlight.

Lunar Eclipse

Occurs when Earth is positioned between the Sun and the moon, causing Earth’s shadow to fall on the moon.
