What advantages do computer models have over physical models? what is an advantage that physical models have over computer models?

Overall mean MRI assessment scores were significantly higher in students utilizing the physical model (86.39%) compared with students using textbooks (62.61%) and the 3D computer model (63.68%) (P < 0.001), with no significant difference between the textbook and 3D computer model groups (P = 0.685). 
physical models advantages
You can understand better your product. 
You can improve it. 
You can have a proof of concept. 
computer models 
The technologically advanced torch shown below has been modelled so that the internal electronic parts can be seen. Making an actual model to display this type of information would be virtually impossible. However, a computer generated model can be animated to show how the parts fit together. the outer casing can be made to look either transparent or translucent. This would be difficult to achieve and be time consuming if a real model was to be manufacture

You can see inside of cumputer models with one click but physical models are also actually there so you can pick it up and get the gist of it better

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Idon't know it i just need my points lol
