Question

Match the law with its correct description:

Answer 1

1. Kepler's 1st law: law of ellipses: - D. The orbit of planets is not circular but elliptical.

2. Kepler's 2nd law: law of equal areas: - B. An imaginary line joining a planet to the Sun sweeps out equal areas in equal amounts of time.

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: - Stationary objects resist movement, and moving objects resist stopping. 

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: - For every action, there is an equal and opposite reaction

7. Newton's law of universal gravitation: - The greater the mass, the stronger the gravitational force.The greater the distance, the weaker the gravitational force

Hope this helps!

Answer 2

Answer :

$(1)\rightarrow D\\(2)\rightarrow B\\(3)\rightarrow G\\(4)\rightarrow E\\(5)\rightarrow C\\(6)\rightarrow A\\(7)\rightarrow F$

Explanation :

1. Kepler's 1st law : It is also known as the law of ellipses. It is defined as the planets moves in an elliptical orbit not in a circular orbit.

2. Kepler's 2nd law : It is also known as the law of equal areas. It is defined as an imaginary line joining a planet to the Sun sweeps out equal areas in equal amounts of time.

3. Kepler's 3rd law : It is also known as the harmonic law. It is defined as the 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  : It is defined as the stationary objects resist movement, and moving objects resist stopping.

5. Newton's 2nd law of motion  : It is defined as the acceleration of an object depends on its mass and applied force.

6. Newton's 3rd law of motion  : It states that for every action, there is an equal and opposite reaction.

7. Newton's law of universal gravitation  : It states that the greater the mass, the stronger will be the gravitational force. The greater the distance, the weaker will be the gravitational force.
