All of the sports at the Winter Olympics in Milano Cortino involve some physics in action. For figure skating, ski jumping ...

Explore the Ball Up/Down Problem from the Feynman Lectures in this clear and engaging physics lesson! This video explains the underlying principles of motion, forces, and energy transfer step by step, ...

Master inclined plane problems using the work-energy method in this detailed physics lesson! This video demonstrates how to apply the principles of work and energy to calculate velocities, forces, and ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

A team at New York University has discovered a new form of time crystal that hovers using sound waves. Unlike ordinary matter, these crystals seem to behave in ways that don’t align with Newton’s ...

During the 2026 Winter Olympics, athletes will leap off ramps, slide across ice and spin through the air. These performances will look different to my students who have studied physics through sports.
