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 idea of the electric field, how it's useful, and explains how the electric field is defined.
This video explains how to find factors.
Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic fields; electric charges or changing magnetic fields cause electric fields.
Magnetism is an interaction that allows certain kinds of objects, which are called ‘magnetic’ objects, to exert forces on each other without physically touching. A magnetic object is surrounded by a magnetic ‘field’ that gets weaker as one moves further away from the object. A second object can feel a magnetic force from the first object because it feels the magnetic field of the first object. The further away the objects are the weaker the magnetic force will be.
Video 1: Introduces the concept of prime factorisation
