What shape is Earth's orbit?
circle
ellipse
square
spiral
What is Kepler's 1st law?
The planets orbit in an ellipse
The plants move faster when they are closer to the sun and slower when they are further from the sun
The farther a planet is from the sun the slower the orbit
(P2 = a3)
What is Kepler's 2nd law?
The planets orbit in an ellipse
The plants move faster when they are closer to the sun and slower when they are further from the sun
The farther a planet is from the sun the slower the orbit
(P2 = a3)
Is the Sun a star?
yes
no
