Learn where the centripetal acceleration formula comes from with a clear, step-by-step derivation. This video explains circular motion, velocity direction changes, and the physics behind the equation, ...

Learn the key physics definitions of position, displacement, velocity, and acceleration explained clearly and simply. This quick breakdown helps build a strong foundation for understanding motion in ...

Velocity is always TANGENT to the path. Acceleration, in general, has BOTH tangential and normal components. The normal component of acceleration always points INWARD to the path. The tangential ...

This module expands on the capabilities for teaching using a Pendulum. A pendulum by itself can provide valuable insight into harmonic motion and the relationship between frequency and period. It can ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

The questions in this quiz are suitable for GCSE physics students studying motion in a straight line, velocity and acceleration, distance-time graphs, velocity-time graphs and velocity, acceleration ...

A ride on a rollercoaster is a perfect example of physics in action. But there is much more at play than simply gravity and speed when it comes to the thrill of rollercoasters, as Michael Allen ...
