planets sweep out equal areas in equal amounts of time

The period squared is equal to the mean distance cubed

The product of the mass is inversely proportional to the distance between the objects squared

lengths stays the same

lengths get longer

lengths get shorter

Lengths get longer then shorter

time stays the same

time speeds up

time slows down

time speeds up then slows down
