# Calculation of Energy Using MATLAB

Question

Perhaps the most famous equation in physics is

E=mc2

Which relates energy E to mass m. The speed of light in a vacuum, c, is the property that links the two together. The speed of light in a vacuum is 2.9979 x 108 m/s.

Create a function called energy to find the energy corresponding to a given mass in kilograms. Your result will be in joules, since 1 kg m2/ s2 = 1J

b) Use your function to find the energy corresponding to masses from 1 kg to 106 kg. Use the logspace function (consult help logspace) to create an appropriate mass

vector.

c) Create a plot of your results. Try using different logarithmic plotting approaches (e.g., semilogy, semilogx, and loglog) to determine the best way to graph your results

Summary

This question belongs to MATLAB software and discusses about application of MATLAB to energy equation in physics and to find out energy corresponding to given mass.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
