Tutorial 3.1
- Introduction: using the vector dot product for rigid body physics problems 0:28
- E.g., ball bouncing off a wall (line in 2D) with an arbitrary inclination
- Using vector operations instead of angles & trigonometry
- What is a dot product? 2:52
- Basically: take vectors j and i: how much does a line j go in the direction of i
- If j and i are perpendicular, their dot product is 0
- How to calculate the dot product 5:54
- Most common usage: "dot with a unit vector" 10:51
- Determines how much a vector is going in the direction of the unit vector
