Match the Laws of Motion

Draggable item		Corresponding Item
Newton's Third Law		An object at rest will stay at rest, an object in motion will stay in motion unless acted upon by an outside force
Newton's First Law		When two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction
Kepler's Third Law		Objects in our solar system orbit in elliptical orbits with one focal point being the Sun
Kepler's Second Law		The closer an object is the the object it's orbiting, the higher it's velocity
Kepler's First Law		The larger the semimajor axis of an orbit, the longer the orbital period.
