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.

in general the data is less accurate than in the simulation

Explanation:

If the measurements were on a real track, some data would be difficult to control, for example the amount of movement. Therefore the results of this parameter would be less reliable.

The bars have a finite width, so that their reading is difficult to match the accuracy of the simulation where the width of the bar is zero.

The other important variable is human error due to several factors, fatigue, parallax, response time, which in the simulation does not exist

The launch speeds of the car by hand have variations due to changes in the person, which in the simulation is always the same
