Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is: ...

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 ...

Actually, that t should really be a Δt.But let me go ahead and show the two graphs for velocity and position that go along with that same acceleration graph above. Actually, let me change 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 ...

I wrote this as a the magnitude of the acceleration and change in velocity so it matches up with our graph. Since the graph is velocity vs. time, the change in velocity divided by the change in ...

Given Bolt’s times for each 10-meter split in the 2008 100-meter race, you can first plot a graph which shows Bolt accelerating for the first 60 meters, ... Using calculus to figure out Usain Bolt’s ...
