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 ...

The equation says, "At time t, you accelerate at a rate proportional to the difference in speed between your car and the speed of the car you're following, but with a gap of T seconds." Put simply, if ...

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The ...
