In this video, we break down the physics behind a tipping or sliding block! Learn how to calculate torque and friction to determine the exact moment when a block will tip or slide. Whether you're ...

This acts when an object is at rest and prevents it from starting to move. It increases up to a certain limit as you apply an external force to initiate motion. This acts when an object is already in ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...
