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

Scientists draw graphs of data to help analyse a situation. A velocity-time graph of a journey can give information about acceleration (the gradient) and distance travelled (displacement).

Now that I have the angular velocity of the planet, I can just calculate its position in each time step as: Really, it doesn't matter what values you use for G and M.

At the Porsche test track, we learn the difference between speed and velocity. Unit 2 Segment B: Speed and Velocity We head to the Porsche test track to learn about the difference between speed ...
