Physicists use the displacement formula to find an object's change in position. It sounds simple, but calculating displacement can quickly get complicated. Let's break it down using some solved ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

The only difference between velocity and speed is that velocity has a direction, and so is a vector quantity. Average velocity = \(\frac{\text{displacement}}{\text{time}}\) Displacement is the ...

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 ...

When adding vector quantities remember that the directions have to be taken into account. The result of adding vectors together is called the resultant. In problems, vectors may be added together by ...
