How objects behave when they are moving back and forth, such as a person swinging on a swing.
Electric Charge
A fundamental measurement in electricity.
Electric Fields
Electricity is often described by the electric field.
Electric Potential
Since electrostratic force is conservative, the concept of potential energy can be applied here.
Magnetic Fields
Similar to how we had described the electric field as an invisible field that exists around every charge, the magnetic field is an invisible field that exists around magnetic particles.
Sources of Magnetic Fields
Electricity and magnetism have a fundamental relationship with each other: magnetic fields are created by moving electric charge.
