Match the term with its definition

Draggable itemarrow_right_altCorresponding Item

The horizontal radius of an elliptical orbit

arrow_right_alt

Eccentricity

The point in an orbit farthest from the Sun

arrow_right_alt

Major Axis

The calculated measure of how circular or oval shaped an orbit is

arrow_right_alt

Minor Axis

One of the center points of an ellipse (in our solar system, one is the Sun)

arrow_right_alt

Perihelion

The vertical diameter of an elliptical orbit

arrow_right_alt

Aphelion

The amount of time it takes for an object to make a complete orbit

arrow_right_alt

Focal Point

The attractive force determined by the mass of 2 objects and the distance between them

arrow_right_alt

Orbital period

Match the Laws of Motion

Draggable itemarrow_right_altCorresponding Item

Kepler's First Law

arrow_right_alt

An object at rest will stay at rest, an object in motion will stay in motion unless acted upon by an outside force

Kepler's Third Law

arrow_right_alt

When two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction

Kepler's Second Law

arrow_right_alt

Objects in our solar system orbit in elliptical orbits with one focal point being the Sun

Newton's Third Law

arrow_right_alt

The closer an object is the the object it's orbiting, the higher it's velocity

Newton's First Law

arrow_right_alt

The larger the semimajor axis of an orbit, the longer the orbital period.
