Step 1I'll help you match the statements to the correct laws.
I'll solve this systematically:
Step 2: Identify Kepler's Laws
- 3rd Law (Harmonic Law): $$\frac{P^{2}}{a^{3}} = \text{constant}$$, where $$P$$ is orbital period and $$a$$ is semi-major axis
- 2nd Law (Law of Equal Areas): \text{A line segment joining a planet and the Sun sweeps equal areas in equal times}
Final Answer
- Kepler's 1st Law: "The orbit of planets is not circular but elliptical." - Kepler's 2nd Law: "An imaginary line joining a planet to the Sun sweeps out equal areas in equal amounts of time." - Kepler's 3rd Law: "Planets closer to the Sun orbit it in a shorter time period than planets further from the Sun." - Newton's 1st Law: "Stationary objects resist movement, and moving objects resist stopping." - Newton's 2nd Law: "Acceleration of an object depends on its mass and applied force." - Newton's 3rd Law: "For every action, there is an equal and opposite reaction." - Gravitational Law: "The greater the mass, the stronger the gravitational force. The greater the distance, the weaker the gravitational force."
