An animation is being created with a thousand tennis balls falling out of a truck, bouncing off the ground and each other. The animator wants to make the scene realistic but also wants to be efficient in the program. Which of these characteristics could be ignored when establishing boundary conditions for the system?
Newton's laws of motion
the diameter of the tennis balls ***
aerodynamic properties
gravitational forces
When establishing boundary conditions for the animation, the animator can ignore the diameter of the tennis balls. The diameter of the tennis balls is not necessary to determine the broad behavior of the animation, such as the motion, interactions, and collisions of the tennis balls, as well as their relationship with the truck and the ground. Since the animator aims for efficiency in the program, focusing on the broad behavior rather than specific details will save computational resources and time. Therefore, the diameter of the tennis balls can be considered as a characteristic that could be ignored when establishing the boundary conditions for the system.
