This question, the title means that there are n balls from the height of the place of H, every second to drop a ball, ball and ball and the ball and the floor are directly elastic collision, the T-seconds after the position of each ball, that is, the height.This problem, similar to ants, that is, the ball and the ball collision can be used as a non-conversion direction, continue to follow the original direction. That is, when r = 0, ignore the radius, calculate the position of each ball, each ba

-trigger.Summary: The classification of objects in physical systems: Triggers (collider components are checked for is Trigger), obstructions (only collider components), movable obstructions (with collider and rigidbody components and Rigidbody components checked for IS kinematic), rigid body (with both collider and rigidbody components)Triggers do not produce any physical interaction. Obstacles are stationary, which can block other body movements.Removable barriers can drive other rigid bodies o

In the universe, from one place to another, the manned space machines currently manufactured by humans can only be flown within the solar system. The universe, discovered through astronomical telescopes and other celestial devices, has a large space, even if people create machines that fly at the speed of light, and consume people for 100 years, and may not be able to reach

Application of physics knowledge in iOS Animation: Angry Birds-Collision Detection and ios Collision DetectionCollision Detection Source code: https://github.com/Esdeath/07-13- I believe that iOS players are more or less familiar with the ball play game. The trajectory of a different point can be changed. For many people, if they do not know the idea, they may think that the ball hits the screen, and it seems difficult to change the movement direction

See the example in exmaples: collisiondetectionexample and see the following: In fact, this example is very similar to drawing a virtual game joystick. The difference is that there are two Sprite in the middle. The key statement for determining the collision is as follows: Scene. registerupdatehandler (New iupdatehandler () {// register an updatehandler in the scenario. Every update is run once @ overridepublic void reset () {}@ overridepublic void onupdate (final float implements condselapsed

Although you will usually back up some important files before reloading the system, but often will miss back up some of the files before, but also some of their own use of the computer's "personal preferences", some of their useful small software, and so they really enjoy the time but found that you have been forgotten in the

This section provides you with a knowledge of the physics game and explains the writing of a simple round free fall demo. The gravity system to be introduced in this paper is actually similar. In a gravity sensor, although I also realized that a circle has different speeds depending on the angle of the phone's reversal, its built-in acceleration algorithms are all encapsulated by the Android OS, and today we're going to talk about a gravity system th

Back to "flash Basic Theory Class-Catalog" We all want technical books that can sneak deep, from simple to complex. The complexity of the content in this chapter reaches its peak. It's not that the next chapters are going to get easier, but I hope you don't cut corners when you're learning this chapter. I will take you step-by-step to learn the concept of this chapter, if so far everyone can keep up with my pace, that would be better. In this chapter we want to focus on momentum: what happens

Statistics are done through the Sql-trace platform we develop or through performance_schema.events_statements_summary_by_digest.

After each landing, it jumps back to half of the original height, then drops, and then rebounds. Ask how many meters a total of 10th landing times, how high the rebound of 10th times.
