Today we continue on our journey of understanding motion, direction, and velocity. Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of ...

Students learn to distinguish between scalar and vector quantities. Introduction to Vectors: Students learn to distinguish between scalar and vector quantities and how to state the magnitude and ...

Atoms are composed of three particles with an electric charge: electrons, protons and uncharged neutrons. Electrons have a negative charge, and protons have a positive charge. The negative charge of ...

In this video, we explain vectors and derivatives as essential math methods used in physics, showing how they describe motion, direction, and change. Clear explanations and examples help connect ...

Multiple forces act on an object at the same time. The size and direction of these forces determines the movement of the object. Show the forces acting on an object in a free body diagram. The arrows ...

Figure 1: Schematic of the 3D force detection method on a Ge(001)-c(4 × 2) surface using bimodal AFM. Figure 2: Force component maps and force vector distributions above Ge(001) dimers. Figure 3: ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
