Does orbital motion really follow a simple mathematical law? 🛰️ This video shows how to verify Kepler’s Third Law for circular orbits, connecting orbital period and radius through gravitational ...

In this video, we solve a classic AP Physics 1 ramp to projectile motion problem step by step, showing how energy, kinematics, and motion concepts connect. Ideal for exam prep and for students looking ...

A school bus is travelling at 4 m/s. Its velocity then increases to 12 m/s. Calculate the average velocity of the bus over the journey. Final velocity = 12 m/s. Initial velocity = 4 m/s. Average ...

When an object changes velocity, it accelerates. Acceleration is the change in velocity per second and is measured in m/s 2. Acceleration is a vector quantity because it has size and direction. The ...

Mark Thomson takes the reins at the CERN particle-physics lab, which recently received $1bn in private donations for its next collider project, as Michael Banks reports Bigger and better: The Large ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...
