% Test formula to calculate translational kinetic energy of a moving object  

%%%%%%%%%%%%%%%%%%%%%%%%
% define the tolerance %
%%%%%%%%%%%%%%%%%%%%%%%%

% tolerance is "how far away from the expected value" the result
% is allowed to be.  Since the calculation involves few approximations,
% the tolerance should be small.

tolerance = 0.0001;

%%%%%%%%%%%%%%%%%
% Run the tests %

  disp('test 2 failed');
