Question

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.

Explanation:

In real - world experiments compared to simulations, there are many factors that can affect data quality. Variables may be hard to control, measurement tools like meter sticks have limitations, real collisions can have energy loss, and human error in data recording can occur. Stopwatch data may not be as valid as simulation - recorded data, and hand - controlling glider velocities is less accurate than simulation controls.

Answer:

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.
