Material Motion - Introduction to the Responsive Principle

Recently the design team at Google updated the Material specification to describe detail about using Motion effectively. The specification is broken down into 4 main principles, in this video, I will be introducing the 1st one, named "Responsive"

The specification formally defines "Responsive" to mean: Material is full of energy. It quickly responds to user input precisely where the user triggers it._

An excellent way to visualize this principle, is to look at "Ripple" touch feedback. I will demo proper "Responsive Motion" using Ripple and Elevation touch feedback. This is a great way to demonstrate two important details about this principle: Ink ripples confirm user input by immediately expanding outward from the point of touch. The card lifts to indicate an active state.
