Physics Physics is the study of energy and matter in space and time and how they are related to each other. Physicists assume the existence of mass, length, time and electric current and then define (give the meaning of) all other physical quantities in terms of these basic units.

General Physics Physics is the study of the laws that govern the universe, and to the best of our knowledge, those laws are the same here and now as they were long ago and far away. In order to explain what we see in the night sky, therefore, we appeal to theories originally developed to explain physical phenomena on the Earth.

Physics for Kids Speed is the magnitude of velocity. Velocity is the speed of an object plus its direction. Speed is called a scalar quantity and velocity is a vector quantity. The fastest possible speed in the universe is the speed of light. The speed of light is 299,792,458 meters per second.

What Is Motion in Science? Motion can be defined as a change in the position of a body with respect to time and another body. Motion is relative in physics. Motion and rest are fundamental ideas in physics. There is no absolute rest as all bodies in the Universe are in a perpetual state of motion. Stars, planets, constellations and even galaxies are in motion with respect to each other.Planets revolve around stars and galaxies move away from each other.

Airbus A380 take-off distance | One-dimensional motion | Physics | Khan Academy Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry. Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations.

Physics for Kids Science Physics for Kids. Current is the flow of an electric charge. It is an important quantity in electronic circuits. Current flows through a circuit when a voltage is placed across two points of a conductor. The flowing of electric current through a wire can sometimes be thought of like the flowing of water through a pipe. 2  The electrical conductivity of a material is the measurement of the ability of the material to allow for the flow of electrical current.

Forces and Motion Facts for Kids Video Forces and Motion Facts for Kids Video. Motion makes all the things go ‘round’. When we think of motion, we often think of cars, bicycles, kids running, basketball bouncing and airplanes flying. But motion is so much more. It is important to our lives and impacts so many things that we do.

- Physics 1. Mechanics Overview. Mechanics is the branch of Physics dealing with the study of motion. No matter what your interest in science or engineering, mechanics will be important for you - motion is a fundamental idea in all of science. Mechanics can be divided into 2 areas - kinematics, dealing with describing motions, and dynamics, dealing with the causes of motion.
