Webb3 apr. 2024 · If it is a pendulum, amplitude must be small because the “time period does not depend on amplitude” rule applies to pendulums only if it is exhibiting simple harmonic motion. So, when amplitude is kept small (allowing use of the #sintheta = theta# approximation), time period is independent of amplitude.

WebbA 'small angle' is equally small whatever system you use to measure it. Thus if an angle is, say, much smaller than 0.1 rad, it will be much smaller than the equivalent in degrees. More typically, saying 'small angle approximation' typically means $\theta\ll1$, where $\theta$ is in radians; this can be rephrased in degrees as $\theta\ll 57^\circ$. can you view shared mailboxes in owaWebbRULE: DIAGRAM: Angle sum of triangle: Add to 180 degrees: Equilateral triangle: All angles equal 60 degrees: Isosceles triangle: Base angles are equal: ... sum of the two interior opposite angles.
