What does modeling and simulation mean in science?
Many times in the sciences, an experiment will be run and observations will be made. Scientists like to be able to estimate and explain those observations, and to do that, they will often come up with a mathematical or causal relationships which attempt to explain these observations in terms of other things which we are more familiar with. The relationships themselves form the model. Once we have a model, we can attempt to make predictions of how observations will turn out, and we can test the accuracy of our model by checking how close we are. Simulation one way of attempting to predict observations. In simulations (as opposed to emulations), a scientist or engineer will attempt to recreate the underlying mechanisms that govern a system. For example, to predict the paths of objects in space, scientists may simulate a model of the solar system. This model can be simple or can be very detailed, and will have to take into account things like the masses of objects, gravity, pressure from stellar winds, tidal friction,etc. The model will have taken into account all of these different factors to come up with an equation for the objects as a function of time. The simulation's job is to solve these equations (perhaps repeatedly for different points in time). An emulator (as opposed to a simulator), is something which will attempt to recreate the outwardly measurable properties of the system. This means that simulators are emulators, but emulators are not necessarily simulators. For example, in a computer game you can emulate gravity simply by having all objects accelerate downwards at the same rate. A simulator for the same thing, however, would need to first take into account the masses and locations of all objects, determine the field strength, and then calculate an acceleration for each item based on the calculated fields.
A system of ideas that explains many related observations and is supported by a large body of evidence is a?
law
Momentum of a system is conserved only when?
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
Heat will flow from a hot object to a cold object until the objects reach what?
In a closed system, yes. Both objects will be at the same thermal energy level, and neither will be able to release any to the other. In the real world, this is not the case, heat would continue to dissipate until the object reaches the same thermal energy level as the air around it, approximately.
The Cartesian coordinate system can be used to measure three-dimensional objects?
TRUE APEX ftw
Who made the first oberservations of objects in the solar system that orbited neither the sun nor earth?
Galileo
What did Galileo Galilel discoverer?
Galileo Galileo discovered the objects in the solar system orbited the sun not the earth
Why is Jupiter like a miniature solar system?
The solar system has one central object, the sun, which is orbited by a large number of smaller objects, the planets, comets, etc. Jupiter is also orbited by a large number of objects, its satellites, which are much smaller than it.Because Jupiter has about 67 moons.
Where did voyajer 1 and 2 get sent to?
They were sent out of the solar system, but orbited around a few planets and studied them for a while. Neither of them are out of the solar system yet, but voyager one, I beilieve, is past pluto.
What orbits the central object of your solar system?
The Sun is the central object in the Solar System; it is orbited by planets, asteroids, meteors, dust particles, and comets.The Sun is the central object in the Solar System; it is orbited by planets, asteroids, meteors, dust particles, and comets.The Sun is the central object in the Solar System; it is orbited by planets, asteroids, meteors, dust particles, and comets.The Sun is the central object in the Solar System; it is orbited by planets, asteroids, meteors, dust particles, and comets.
Why don't objects in the solar system travel straight?
The gravity of the sun (or whatever object is being orbited) keeps a force pulling the planets inward, allowing them to stay in orbit and not fly off.
What was found by astronomers who noticed a strange pattern in the orbit of Uranus?
Neptune
What is a frame of reference?
A frame of reference is a coordinate system used to define the position and motion of objects. It provides a point of view or context from which observations are made and measurements are taken. Different frames of reference can yield different descriptions of the same event, depending on the observer's perspective.
What was Copernicus view of the solar system?
he thought the sun was in the center of the solar system, and that all the other planets and Earth orbited around it
How did Galileo's observations of jupiters moons help to show that the geocentric explanation is incorrect?
Galileo reasoned that the phases of Venus could not be explained, if the Earth is in the center of the system of the planets. So Ptolemy's geocentric system could not be correct. Edit: That's correct, but it doesn't answer the question, which is about Jupiter. The idea is that Jupiter having moons proved that there are other places that can be centres of motion, apart from Earth.
What was the old model of the solar system called?
geocentric model, where the sun and other planets orbited the Earth.
How is the solar system similar to the bohr?
Both the solar system and the Bohr model of the atom have a central body (Sun or nucleus) orbited by smaller objects (planets or electrons) in defined paths. They both follow similar principles of circular motion and gravity/electromagnetic force governing the interactions between the central body and the orbiting objects.
