Measuring Motion: Speed and Acceleration

Basic objective of this lecture is to present on Measuring Motion: Speed and Acceleration. Example; Measuring Distance: Meter – international unit for measuring distance. Calculating Speed: Speed (S) = distance traveled (d) / the amount of time it took (t). Velocity and speed are very similar ideas, but velocity is a vector, and speed is not. When velocity is changing, the word acceleration is used. Acceleration is also a vector. You speed up if the acceleration and velocity point in the same direction.
