Rotational motion can feel tricky, but with the right approach, it becomes a powerful tool in your physics toolkit. From angular velocity to torque, understanding these concepts is key to solving real ...

Ask any engineer what the velocity of a point on a rigid body is, and they will correctly say that it's the time rate of change of a linear position vector. Ask any engineer what angular velocity is, ...

I love using seemingly random data to figure out stuff I wouldn't otherwise know. You can do this with all kinds of things, but in this example, I use video that I recorded from an airplane to figure ...
