Physics is the science that studies the fundamental laws and principles that govern the natural world.
Who is considered the father of physics?
Sir Isaac Newton is considered the father of physics.
What are the main branches of physics?
The main branches of physics are classical mechanics, electrodynamics, thermodynamics, and quantum mechanics.
What is the law of gravity?
The law of gravity states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
What is the speed of light in a vacuum?
The speed of light in a vacuum is approximately 299,792,458 meters per second.
What is the law of conservation of energy?
The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed from one form to another.
What is the unit of electric charge?
The unit of electric charge is the coulomb (C).
What is the law of reflection?
The law of reflection states that the angle of incidence is equal to the angle of reflection, measured with respect to the normal to the reflecting surface.
What is the first law of thermodynamics?
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed.
What is the principle of conservation of momentum?
The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces are acting on it.
What is the SI unit for force?
The SI unit for force is the newton (N).
What is the difference between speed and velocity?
Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that measures both speed and direction of motion.
What is the law of conservation of mass?
The law of conservation of mass states that the mass of a closed system remains constant over time, as long as no mass is added or removed.
What is the law of electric charges?
The law of electric charges states that like charges repel each other, while opposite charges attract each other.
What is the formula for kinetic energy?
The formula for kinetic energy is KE = 0.5 * mass * velocity^2.
