Foundational Physics Concepts

Equations can be a bit boring, so FlippedPhysics uses basic geometry to illustrate the derivation of five equations of constant acceleration in this lesson.

In physics, the x- and y-dimensions tend to be looked at separately. To help wrap your head around this, watch a demo with balls going in different directions.

Learn how to solve problems in two dimensions with vectors! Follow a simple example in this lesson to see how to break velocity down into its components.

When was the last time you had an epiphany sitting under an apple tree? In this physics lesson, learn Newton's First Law, and review the definition of force.

In physics, mass and weight refer to two different measurements! David defines mass and weight, and explains how these quantities relate to gravity.
