Basic Physics SE-Units
This chapter covers the basic units used in physics, guidelines for using units, and their importance within physics.
Basic Physics SE-SHM Wave
This chapter covers objects in harmonic motion, which are defined as objects that return to the same position after a fixed period of time. Objects in harmonic motion have the ability to transfer some of their energy over large distances.
Basic Physics SE-Light Nature
This chapter covers the nature of light, polarization, and color.
Basic Physics SE-Optics
This chapter covers reflection, refraction, mirrors and lenses, and these concepts apply to Fermat's principle.
Basic Physics SE-Motion
This chapter covers the speed and velocity of objects in space. Velocity is speed with a direction, making it a vector quantity. If an object’s velocity changes with time, the object is said to be accelerating.
Basic Physics SE-Projectile Motion
This chapter covers parabolic motion of a thrown object, known as projectile motion. Motion in one direction is unrelated to motion in other perpendicular directions.
Basic Physics SE-Force
This chapter covers the basics of force as understood through Newton's 1st, 2nd, and 3rd Law of Motion.
Basic Physics SE-Momentum
This chapter covers momentum which is the product of mass and velocity. Momentum can be exchanged from one object to another through a collision.
Basic Physics SE-Energy
This chapter explains energy as a measure of the amount of or potential for movement in something. The total amount of energy in the universe is always the same.
Basic Physics SE-Heat
This chapter explains heat as a form of energy transfer. Materials do not contain heat. They contain internal energy that can be transferred (i.e. heat) from one body to another.
Basic Physics SE-Circular Motion
This chapter covers the basics of circular motion. In the absence of a net force, objects move in a straight line. Forces which cause objects to turn around continuously in a circle are known as centripetal forces.
Basic Physics SE-Gravity
This chapter covers gravity and how it relates to laws of physics governing motion, spcifically the Universal Law of Gravitation.
Basic Physics SE-Electrostatics
This chapter explores the fourth of the 5 conservation laws in physics, the conservation of charge. There are two charges, + and -, and the symmetry of the electric charge indicates that the total charge in the universe remains the same.
Basic Physics SE-DC Electric Circuits
This chapter explores electric currents through voltage and resistance as they apply to Ohm's Law, the main equation for electric circuits.
