The simulation kept track of the variables and automatically recorded data on object displacement, velocity, and momentum. If the trials were run on a real track with real gliders, using stopwatches and meter sticks for measurement, how might the data compare? Check all that apply.- There would be variables that would be hard to control, leading to less reliable data. - The data would be just as valid if it were recorded with a stopwatch. - Meter sticks may lack precision or may be read incorrectly. - Real glider data may vary since real collisions may involve loss of energy. - Human error in recording or plotting the data could be a factor. - Controlling real glider velocities by hand would be just as accurate as simulation controls.
