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 ...

Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact. The gradient of speed-time and velocity-time graphs represent acceleration.

On the graph of velocity vs. time, Δv/Δt is the slope of the curve. If the curve is straight, the acceleration is constant. If the curve isn't straight we have to do the same trick we did before with ...

Why do you always make a graph in physics lab? It's not just for fun ... The x 0 is the starting postion (at t = 0) and v 0 is the velocity at time zero. So, for this case, I will release the ...

The area enclosed by the velocity-time graph, the time-axis and the two coordinates at time instants t 1 to t 2 gives the distance moved by the particle in the time-interval from t 1 to t 2.
