Imagine being trapped at the bottom of a well. In order to escape, one would need to expend energy to climb out. The escape velocity is a measure of the precise amount of energy required to arrive at the mouth of the well. Also referred to as the ‘second cosmic velocity’, the escap...
How do I enable the physics in cococs2d-x? The nice thing about cocos2d-x is that it already comes with everything you need to create cool games. This includes a physics engine called Chipmunk. So everything you need to get the engine running is to initialize it during scene creation: ...
Instead of using the scientific method -- investigating empirical evidence -- to study the quantum level, physicists must use thought experiments. Although these experiments are only carried out hypothetically, they're rooted in the data observed in quantum physics. What science has observed...
Where do black holes lead to? If a massive object crosses the event horizon, it will be sucked into the black hole and never escape. What happens inside the black hole is unknown; even our current theories of physics do not apply in the vicinity of a singularity. What are the two types...
Velocity time graphs show the changes in velocity of objects and allow us to calculate the changes in position and the acceleration of the object. These changes in position can then be used to determine the total distance covered by the object....
Physics fundamentally is interested in the interactions of matter and energy. Since the world that we lived in is composed of matter and energy, physics can be applied to multitudes of systems, even to biological ones. Recently, concepts in Phys...
Here is a complete guide to everything you need to know about how to work and communicate asynchronously in a remote work environment. Learn more!
