Explicação
## Step1The stability of animals and athletes like a cheetah or a standing human is explained by the concept of the center of mass and base of support. The center of mass is the point where the mass of an object is evenly distributed and the base of support is the area where an object rests or is supported. When the center of mass is within the base of support, the object remains stable.## Step2Newton's law of gravitation primarily explains the motion of celestial bodies. This law states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This law is the basis for understanding how objects move in space, including planets and stars.## Step3Astronomers primarily use light years to measure distances of astronomical objects. A light year is the distance that light travels in one year, which is about 5.88 trillion miles (9.46 trillion kilometers). This unit of measurement is used because light travels at a constant speed, and it allows astronomers to measure vast distances in a more manageable way.## Step4Geology is the branch of Earth science focused on the study of Earth's solid and liquid matter. It involves the study of rocks, minerals, and the processes by which they change over time. Meteorology is the study of the atmosphere and weather, astronomy is the study of celestial objects and phenomena, and oceanography is the study of the ocean.## Step5The physics concept used to study the electrical properties, density, and magnetization of minerals is electromagnetism. Electromagnetism is a branch of physics that deals with the study of electric and magnetic fields and their interactions with matter. It is essential in understanding how minerals can exhibit electrical properties and how they can be magnetized.
