Formula 2: Acceleration

a = acceleration (in m/s2)

vf = final velocity (in m/s)
vi = initial velocity (in m/s)
t = time (in seconds)

__________________________________________________________________________

Issac Newton is credited as the Founding Father of acceleration. He was the first scientist to determine that all moving things had its own acceleration. In 1666, Newton's first law stated that the change between the initial velocity and final velocity, also known as acceleration, is "the result of a force acting on the body and change can be caused by either a change in magnitude or direction" (The Space Site).

Numerical example:

If the initial velocity is 24.7 m/s2 and the final velocity is 49.2 m/s2, what is the acceleration after 38 seconds have passed?

Real Life Example:

Wendy is currently living in Tokyo, Japan. She recently visited Regina, who was living in Kyoto, Japan. She took the Japanese Shinkansen line from Tokyo to Kyoto. The train that she rode moved at a final velocity of 31 meters per second. She was curious to find out what the acceleration of the train was, if it took 20 seconds to reach the final velocity from a standing point.
