Answer:
1.) Kepler's 1st law: law of ellipses
____The orbit of planets is not circular but elliptical.
2.) Kepler's 2nd law: law of equal areas
____For every action, there is an equal and opposite reaction.
3. Kepler's 3rd law: harmonic law
____Planets closer to the Sun orbit it in a shorter time period than planets further from the Sun.
4. Newton's 1st law of motion
____An imaginary line joining a planet to the Sun sweeps out equal areas in equal amounts of time.
5. Newton's 2nd law of motion
____Acceleration of an object depends on its mass and applied force.
6. Newton's 3rd law of motion
____Stationary objects resist movement, and moving objects resist stopping.
7. Newton's law of universal gravitation
____ The greater the mass, the stronger the gravitational force. The greater the distance, the weaker the weaker the gravitational force.
