Why is acceleration's formula's denominator squared?
Mar 20, 2025 · The acceleration can change over time and this is why this approximation breaks down if the acceleration changes too much within the time interval. If you want to know more about this kind …
A simple derivation of the Centripetal Acceleration Formula?
Jul 12, 2015 · For this proof I will assume two things The radius is constant, i.e. $\vec r\cdot \vec r=r^2=c$ The acceleration is in opposite direction to the position vector, i.e. $\vec a\cdot \vec r=-ar$. …
What does the magnitude of the acceleration mean? - Physics Stack …
Feb 9, 2014 · The magnitude of the acceleration vector along the path is the time rate of change of speed. The magnitude of the acceleration vector normal to the path is the centripetal acceleration as …

Intuitive explanation for why centripetal acceleration is
Jun 21, 2015 · Acceleration is the derivative of velocity, and we know how to take the derivative. Since the velocity is doing exactly the same thing the position is, we can take the derivative of the velocity …
kinematics - Formula for centripetal acceleration: simple proof that ...
Dec 11, 2020 · I teach physics to 16-year-old students who do not know calculus and the derivates. When I explain the formula for centripetal acceleration in circular uniform motion, I use this picture: …
Why do I get $\\alpha = \\omega ^2$ in angular acceleration?
Sep 9, 2023 · The tangential acceleration of a body in a uniform circular motion is 0 due to the fact that it's magnitude is equal to r (radius) times the angular acceleration (which is zero as the body has a …
Proof of centripetal acceleration formula - Physics Stack Exchange
Jun 21, 2015 · The proper derivation of the centripetal acceleration—without assuming any kinematic variables are constant—requires a solid understanding of both the stationary Cartesian unit vectors i^ …
How to get distance when acceleration is not constant?
The acceleration is obviously not constant, but what about the change in acceleration? Is it constant? I suspect not. And then what about the change in the change of acceleration, etc. etc.? In other words, …
