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 …
Determine acceleration from experiment (Newton 2nd Law)
I have done a physics experiment (setup below). And was asked to determine the experimental and theoretical acceleration. The data I've got Ok, am I right to say Experimental acceleration = $2(...
Intuitive explanation for why centripetal acceleration is $\frac {v^2 ...
Jun 21, 2015 · There are several ways to write centripetal acceleration $$\frac {v^2} {r} = \omega^2 r = v \omega$$ Are there intuitive explanations for any of these three forms?
Acceleration of an object after overcoming static friction
Apr 27, 2023 · According to the standard basic model of friction we learn in introductory physics, at the instant that is starts moving, kinetic friction takes over. The kinetic friction force always has …
Is acceleration $a = s/t^2$, or $a = 2s/t^2$, or something third?
Acceleration is defined as $ a = \frac {s} {t^2}.$ Distance can be calculated as the area under velocity-time line; given a constant accelation, and an initial velocity of 0, this forms a triangle: $ s = \frac …
How to get distance when acceleration is not constant?
This is not realistic. Instead, you will want some way of determining either the velocity or the acceleration as a function of time or position. In physics, it is common to be able to determine the acceleration as …
