Johannes Kepler's Three Laws Of Motion
Create a table with the period and radius in it taken from the database. Data Collection and Processing It is more convenient to draw to graphs than one because there is a large difference in the scale in terms of distance to the sun and time for 1 orbit between the first planet and the last planet. Conclusion and Evaluation As this is not an investigation we cannot really look at any errors, weaknesses or limitations and ways of improving the experiment.

Avoid submitting plagiarized assignments. But how can we best do this? The most efficient method was discovered in by Walter Hohmann, inspired by a popular science fiction novel of that time. The method is now called a Hohmann transfer. As before, the Sun is at the focus of the ellipse. For any ellipse, the semi-major axis is defined as one-half the sum of the perihelion and the aphelion.
In Figure Hence, to travel from one circular orbit of radius r 1 r 1 to another circular orbit of radius r 2 r 2 , the aphelion of the transfer ellipse will be equal to the value of the larger orbit, while the perihelion will be the smaller orbit. From Equation The most efficient method is a very quick acceleration along the circular orbital path, which is also along the path of the ellipse at that point. In fact, the acceleration should be instantaneous, such that the circular and elliptical orbits are congruent during the acceleration.
In practice, the finite acceleration is short enough that the difference is not a significant consideration. Once you have arrived at Mars orbit, you will need another velocity boost to move into that orbit, or you will stay on the elliptical orbit and simply fall back to perihelion where you started. For the return trip, you simply reverse the process with a retro-boost at each transfer point. To make the move onto the transfer ellipse and then off again, we need to know each circular orbit velocity and the transfer orbit velocities at perihelion and aphelion.
The velocity boost required is simply the difference between the circular orbit velocity and the elliptical orbit velocity at each point. We can find the circular orbital velocities from Equation To determine the velocities for the ellipse, we state without proof as it is beyond the scope of this course that total energy for an elliptical orbit is. Remarkably, this is the same as Equation Since we know the potential energy from Equation We leave it as a challenge problem to find those transfer velocities for an Earth-to-Mars trip.
We end this discussion by pointing out a few important details. First, we have not accounted for the gravitational potential energy due to Earth and Mars, or the mechanics of landing on Mars. In practice, that must be part of the calculations. Second, timing is everything. We must leave Earth at precisely the correct time such that Mars will be at the aphelion of our transfer ellipse just as we arrive. That opportunity comes about every 2 years. And returning requires correct timing as well. The total trip would take just under 3 years! There are other options that provide for a faster transit, including a gravity assist flyby of Venus. But these other options come with an additional cost in energy and danger to the astronauts.

Consider Figure The time it takes a planet to move from position A to B , sweeping out area A 1 A 1 , is exactly the time taken to move from position C to D , sweeping area A 2 A 2 , and to move from E to F , sweeping out area A 3 A 3. Comparing the areas in the figure and the distance traveled along the ellipse in each case, we can see that in order for the areas to be equal, the planet must speed up as it gets closer to the Sun and slow down as it moves away.
