In a world full of unbalanced forces (which you learn more about when you study Newton's laws), you will have acceleration (which is the rate in change of velocity). Whether you're thinking about how fast a Porsche can get to 60mph or how long it takes for a passenger plane to get to the necessary speed for flight, this tutorial will help.
Calculating the acceleration of a Porsche
Velocity describes how position changes. Acceleration describes how velocity changes. Two layers of change!
Figuring how long it takes an a380 to take off given a constant acceleration
How long of a runway does an A380 need?
Understanding why distance is area under velocity-time line
See what we can learn from graphs that relate velocity and time.
David explains how to read an acceleration vs. time graph. He then shows how the area under the curve gives the change in velocity and does a few examples.
