Physics is the branch of science that deals with the study of matter, energy, and their interactions. It seeks to understand the fundamental laws and principles that govern the behavior of the universe.
There are several branches of Physics, including classical mechanics, thermodynamics, electromagnetism, optics, and quantum mechanics. Each branch focuses on a different aspect of the physical world and has its own set of principles and laws.
Scalar quantities have only magnitude, while vector quantities have both magnitude and direction. Examples of scalar quantities include distance, mass, and time, while examples of vector quantities include velocity, acceleration, and force.
Speed is the rate at which an object is moving, while velocity is the rate at which an object is moving in a specific direction. Speed is a scalar quantity, while velocity is a vector quantity.
To solve a Physics problem, you must first identify the given information and what you are trying to find. Then, use the appropriate equations and principles to manipulate the given information and solve for the unknown. It is also important to pay attention to units and use conversions when necessary.
