Há 2 dias · Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.
Há 4 dias · Gravity, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest force known in nature and thus plays no role in determining the internal properties of everyday matter. Yet, it also controls the trajectories of bodies in the universe and the structure of the whole cosmos.
Há 4 dias · In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise.
Há 2 dias · contributed. Quantum mechanics [QM] is a branch of physics which describes physical systems so that properties like the energy or angular momentum are discrete quantities that are multiples of a smallest unit or quantum. A famous physicist named Erwin Schrödinger made an example of quantum mechanics, often called Schrödinger's cat.
