There are two components to Velocity; 1) Speed and 2) Direction. A change in either component or both is called “Acceleration.”
I don’t like this. I want to change the nomenclature. The word “Acceleration” should be used only when the Speed component is altered.
Currently, physicists claim that any revolving object– though it may keep exactly the same speed– is constantly “accelerating.” This is simply by definition… Acceleration has been defined as any change in Velocity. Therefore, if the direction of an object changes, it is said to be “accelerating” even when its speed remains the same. As an object revolves, its direction is constantly changing, so it is said to be in a constant state of “acceleration”… without ever getting any faster.
The definitions of Force and Acceleration, have been inextricably bound and twisted together over the centuries. Force is defined as a measure of the Acceleration (taking into account Mass), and vice versa: Acceleration is a measure of Force (taking into account Mass). I posted yesterday why I think there really is no such thing as Force.
Today, I’m gunning for Acceleration. I prefer we have a separate term to use when we are speaking only of a change in direction, with no change in speed. Maybe “transdirection?”
Who knows? Could be that when we start being less messy with our words, we will discover new facets of old processes that we thought we knew.
