Why limit trajectories? #292

Closed matthew-blackman closed 1 year ago

matthew-blackman commented 1 year ago

The sim is limiting the number of trajectories shown at one time. Is there a reason/need for this? Would like to discuss at design meeting.

Also noting that this is particularly pertinent because of our refactor to make a 1 to 1 of Trajectory and ProjectileObject (on said Trajectory) over in https://github.com/phetsims/projectile-motion/issues/291.

This decision should be made on a per-screen basis, based on the pedagogical needs of each. This can be implemented after standards have been agreed upon for the limiting of trajectories.

The sim in its current form does not allow users to show more than 5 simultaneous trajectories, which may be useful if a user wanted to do this for demonstration purposes. Since we have an erase button, do we need to automatically delete trajectories? If so, what is a good maximum number?

Closing this issue pending the next round of design meetings for Projectile Motion - Data Fluency
