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.
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.
