Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

modeling systems for which simple closed form analytic solutions are not possible. There are many different types of computer simulation; the common feature they all share is the attempt to generate a sample of representative scenarios for a model in which a complete enumeration of all possible states of the model would be prohibitive or impossible. Computer models were initially used as a supplement for other arguments‚ but their use later became rather widespread. The Solar System consists of

Proper understanding of each of these discoveries and theories is important when learning about our universe. Planetary Accretion Planetary accretion has two main theories on how the planets in our solar system were formed. The first of the two is the Solar Nebular Disk Model; this is where our Solar System’s planets started out as small pieces and started to collide together‚ uniting into bigger pieces and this kept happening until they became planetesimals. Once they were planetesimals‚ they crashed

SOLAR SYSTEM About 5 Billion years ago‚ y There was no Sun‚ no Earth& no Moon y Only cosmic dust and gasses drifted in the darkness of space SOLAR SYSTEM THEORY The solar system was formed by a slowly spinning cloud of gas and cosmic dust‚ gradually the cloud began to spin faster and faster this formed a large spinning whirl at the centre and smaller whirls surrounding it at various distances. SOLAR SYSTEM THEORY The huge and heavy centre became hot enough to start thermo nuclear

My Solar System Name Period Introduction: Every physics student has had a lot of experience with the force of gravity. Unfortunately‚ this experience is limited to the interaction between a very large object‚ the Earth‚ and much smaller objects that are very close to it. This is a very limited range of the possibilities. Software simulations of gravity allow physics students to explore a variety of other gravitational interactions between objects. These activities are designed to be used

Using the data from your experiment‚ describe why you believe your hypothesis was either proved or disproved. What forces were acting on the objects dropped in the air? What force was acting on the objects dropped in the vacuum? Analysis and Conclusions: In your own words‚ write an analysis of the differences between the acceleration rate of objects on Earth versus objects in the vacuum of space. Be sure to include terminology from the lesson and direct references to your data. If the paper
