Equation of SHM is $x=10\sin{10\pi t}$. Find the distance between the two points where speed is $50\pi$ $cm/sec$. $x$ is in cm and $t$ is in seconds
Which of the following equation does not represent a simple harmonic motion:
What is the number of degrees of freedom of an oscillating simple pendulum?
All oscillatory motions are ______
Simple harmonic oscillation of a given system can be specified completely by stating its:
Simple harmonic motion (SHM) is a technical term used to describe a certain kind of idealized oscillation. Practically all the oscillations that one can see directly in the natural world are much more complicated than SHM. Why then do physicists make such a big deal out of studying SHM?
Which of the following conditions must be satisfied for a body to oscillate or vibrate?
A: The body must have inertia to keep it moving across the mid point of its path.
B: There must be a restoring force to accelerate the body towards the midpoint.
C: The fractional force acting on the body against its motion must be small.
An object swinging on the end of a string forms a simple pendulum. Some students (and some texts) often cite the simple pendulum's motion as an example of SHM. That is not quite accurate because the motion is really
