How did Newton’s Law of Gravity explain why celestial objects stay in orbit?

a
A combination of the forward motion of the objects and the pulling force of gravity create the rounded orbit shapes
b
Gravity pushes objects across circular paths by attracting them to ellipses
c
Newton explained how gravity creates the foci that objects orbit around
d
Objects need the force of gravity to continue moving in the current orbit directions they were already moving in
