Foundational Physics Concepts

Equations are at the heart of physics! This lesson presents ways to write equations for scenarios in which forces like gravity and friction are in balance.

When you're in an elevator, can you tell you're moving? The answer to this physics question, clearly, involves forces! Learn to calculate force in newtons.

When a car and fly collide, why is the car fine while the bug is obliterated? Newton's third law of motion offers offers a clue, but the answer is surprising!

FlippedPhysics walks you through the basics of inclines, starting with a simple diagram and graph to illustrate the forces moving a ball down a hill.

FlippedPhysics explains the difference between static and kinetic friction, the equation for frictional force, and demonstrates how powerful friction can be!
