Kepler's First and Third Laws Quick Check
Hi! please keep in my mind that answers vary for each school.
and be careful not to fall people who use false answers
1. Which planet’s orbit was Kepler first studying when he began to develop his laws of orbital motion?
A. Mars
2. Which of these describes Kepler’s third law of orbital motion?
A. T2 ∝ a3
3. Which orbital shape did most scientists in the early 1600s think the planets of our solar system have?
A. circular
4. Which is the best description of Earth’s orbit?
A. almost circular
5. Which statement describes Kepler’s third law of orbital motion?
A. The square of orbital period is proportional to the cube of the semi-major axis.
Hope this help! an goodluckkk
100% thanks
100% thanks love ya 🧍🏾
100% !!!
I can confirm, this is indeed correct
To answer these questions, we need to understand Kepler's First and Third Laws of orbital motion. Here's how you can get the answers:
1. Kepler first studied the orbit of Mars when he began developing his laws of orbital motion. To find this answer, you can research historical accounts of Kepler's observations and investigations.
2. Kepler's third law of orbital motion is described by the equation T^2 ∝ a^3, where T represents the orbital period and a represents the semi-major axis of the orbit. To determine which option describes Kepler's third law, you can compare the provided equation with the options given.
3. In the early 1600s, most scientists thought that the planets of our solar system have circular orbits. To find this answer, you can study historical records, scientific literature, or research the prevailing understanding of planetary orbits during that time period.
4. Earth's orbit is described as almost circular. To confirm this, you can refer to scientific sources or astronomical data that clearly describe the shape of Earth's orbit.
5. The statement that describes Kepler's third law of orbital motion is: "The square of the orbital period is proportional to the cube of the semi-major axis." To find this answer, you can compare the options provided with the description of Kepler's third law that you have learned.
Remember to fact-check the information from reliable sources as different schools or regions might have variations in their teachings. Good luck with your quick check!
1. Well, Kepler was not really playing favorites here, but he was studying the orbit of Mars when he started developing his laws. So, the answer is A. Mars. Although, I'm sure he also had a soft spot for Jupiter's stylish red spot.
2. Kepler's third law can be summed up with a little algebraic equation - T2 ∝ a3. In more understandable terms, it means that the square of the orbital period is directly proportional to the cube of the semi-major axis. So, the answer is A. T2 ∝ a3. And yes, there will be a pop quiz on algebraic equations later.
3. Back in the early 1600s when perms were all the rage, most scientists actually believed that the planets in our solar system had circular orbits. They were all about that symmetry. So, the answer is A. circular. They were just ahead of their time in embracing the shape trend.
4. Earth's orbit is like that one friend who always tries to be different but ends up being almost circular. So, the answer is A. almost circular. It's like Earth wanted to fit in with the other planets but was too cool to be a perfect circle. You go, Earth!
5. Kepler's third law is all about being proportional. The square of the orbital period is directly proportional to the cube of the semi-major axis. So, the answer is A. The square of the orbital period is proportional to the cube of the semi-major axis. This law is like the math version of a balanced relationship - everything in perfect harmony.
I hope that helps and remember, if all else fails, just make some funny faces and people will forget what the question was. Good luck!
