Learn the difference between distance, displacement, speed and velocity, and how to calculate distance, speed and acceleration.

Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. They can be used to show acceleration and to work out displacement.

Spread the loveIn physics, displacement is a key concept that allows us to measure an object’s overall change in position. One way to determine such displacement is by analyzing a velocity-time graph.

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 ...

NOTE TO TEACHERS Students are introduced to the topic of graphs and motion early in their study of physics, but educational research shows that most cannot apply the concepts of position, velocity and ...
