Vocabulary:

Universal Law of Gravitation: Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Gravitational Force: A force that attracts any objects with mass. It is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another.

Inverse Square Law: A law stating that the intensity of an effect such as illumination or gravitational force changes in inverse proportion to the square of the distance from the source.

Orbital Period (days): This is the time in Earth days for a planet to orbit the Sun from one vernal equinox to the next. Also known as the tropical orbit period, this is equal to a year on Earth. * For the Moon, the sidereal orbit period, the time to orbit once relative to the fixed background stars, is given. The time from full Moon to full Moon, or synodic period, is 29.53 days. For Pluto, the tropical orbit period is not well known, the sidereal orbit period is used.

Orbital Velocity (km/s or miles/s): The average velocity or speed of the planet as it orbits the Sun, in kilometers per second or miles per second.

Distance from Sun (10⁶ km or 10⁶ miles): This is the average distance from the planet to the Sun in millions of kilometers or millions of miles, also known as the semi-major axis. All planets have orbits which are elliptical, not perfectly circular, so there is a point in the orbit at which the planet is closest to the Sun, the perihelion, and a point furthest from the Sun, the aphelion.

Rotation Period (hours): This is the time it takes for the planet to complete one rotation relative to the fixed background stars (not relative to the Sun) in hours. Negative numbers indicate retrograde (backwards relative to the Earth) rotation.

Density (kg/m³ or lbs/ft³): The average density (mass divided by volume) of the whole planet (not including the atmosphere for the terrestrial planets) in kilograms per cubic meter or pounds per cubic foot.

Radius: a straight line from the center to the circumference of a circle or sphere.

Revolution: The movement of one object around a center or another object, a forceful overthrow of a government by the people or any sudden or grand change. An example of revolution is movement of the earth around the sun.

The Gravitational Constant: Is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's general theory of relativity.

Convection: Is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Convection includes sub-mechanisms of advection, and diffusion.

Earth's Magnetic Field: Also known as the geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.

Radioactive Decay: The process by which an unstable atomic nucleus loses energy by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion.

Crust: The outermost solid shell of a rocky planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase.

Mantle: A layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density.

Liquid Outer Core: The outer core of the Earth is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.

The Earth's Inner Core: is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometers (760 miles), which is about 70% of the Moon's radius. It is composed of an iron–nickel alloy and some other elements.

Learning Target

Right now I think I overall understand the topic but tend to do better with help or a sheet of notes. Something I am completely confident in is Newton's Law of Gravitation. I think I am a level four, meaning that I could easily teach someone else how to do this because I understand it. Something I am decent at is predicting orbits of the planets. It honestly just depends on what info I was given and if I was able to think it threw. I do not think I could teach someone this and need more help understanding it myself.

Reflection:

I think I worked pretty well on this project. I helped contribute to my team and split the workload when it came to working on the poster. Something I thought I could done better for this project was taking a leadership role. For this project I was very laid back and went with the flow. I did not suggest my ideas as much as I could have and could have contributed more. This would have helped my group move faster and get more done. Also I could have helped encourage my group when we got stuck on it a problem. Instead I stayed confused with my group.

Something I did well was my time management. I completed all of my work to the best of my abilities. I knew how to split up the work each day so I could get it done in time and well. Also when it came to model five , I made sure to complete my work well and complete it with enough time to spare to help my partner. To do this I stayed focus the majority of the period and stayed at my table. I did not talk to people until I got my work done and only left my seat a couple of times. This project was fun and can't wait for more like it in the future.
