Kepler's Laws Vocabulary

Kepler's 2nd Law deals with 

• the shape of the planets' orbits

• the speed/area the planet travels 

• the length of time it takes the planet to orbit the sun

Which answer choice best describes kepler's 1st law

• Space travel is limited by the speed of light and gravitational forces

• Each planet orbits the sun in an ellipse rather than a circle

• Each planet orbits the sun in a circle

• The earth's edges have a heliocentric model

Kepler's 1st Law says this about the orbits of planets

• they are elliptical.

• they are perfect circles.

• they are always perfect polygons (square, pentagon, hexagon, etc.,)

• they are parabolic.

Kepler's 3rd Law states that the farther away a planet is from the sun, the _______ it takes it to orbit the sun once (year).

• longer

• shorter
