This content provides a step-by-step solution for calculating the torque on a particle about the origin, given its position vector and an applied force vector, using unit-vector notation. It then demonstrates how to find the angle...

Learn the basics of vector physics, including how to add vectors and interpret their graphical representation. Understand the difference between scalar and vector quantities with real-world examples.

This is an introduction to relative velocity. There is an animation at the end which helps highlight that the motion of a rigid body can be split into both rotational and translational movement. I also show (informally) that the velocity...

This question really tests your ability to apply the relative motion formula Va/b = Va - Vb. A few consequences of this are that the bottom of the wheel rotating has an instantaneous velocity of 0m/s ! Something that might be very...

It explains how to find the angle between a line and a plane when their vector equations or Cartesian equations are given.
