In this course you will learn about:
This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work.
The Earth behaves like a giant bar magnet and as such there is a magnetic field present around it. The Earth’s magnetic field is thought to be caused by flowing liquid metals in the outer core of the planet which causes electric currents and a magnetic field.
The idea of the electric field, how it's useful, and explains how the electric field is defined.
This video explains how to find factors.
By the end of this lesson you will be able to:
saac Newton (1642–1727) was a natural philosopher; a great thinker who combined science and philosophy to try to explain the workings of nature on Earth and in the universe. His laws of motion were just one part of the monumental work that has made him legendary. The development of Newton’s laws marks the transition from the Renaissance period of history to the modern era. This transition was characterized by a revolutionary change in the way people thought about the physical universe. Drawing upon earlier work by scientists Galileo Galilei and Johannes Kepler, Newton’s laws of motion allowed motion on Earth and in space to be predicted mathematically.
Short Physics tutorial on Forces. On completion you will be able to
Introduction to magnetism: Wikipedia article that provides an overview of the concept.
