Sample Question 1
What is the fundamental goal of an N-body simulation in astrophysics?

To measure the brightness of a single star

To calculate the individual gravitational interactions between many different objects over time

To find the chemical composition of a planet

To count the number of atoms in a vacuum

To predict solar eclipses using only light data

Sample Question 2
There is a general, closed-form algebraic solution that can perfectly predict the positions of three or more bodies for all of eternity.

True

False

Sample Question 3
Why does the computational cost of n body simulations explained in computer science grow as N^2?
