Simple Harmonic Motion (SHM)
Simple Harmonic Motion or SHM. It is a special case of oscillation, along with a straight line between the two extreme points (the path of SHM is a constraint). The path of the object needs to be a straight line. There will be a restoring force directed towards the equilibrium position (or) mean position.
What are the kinematic formulas? (article) | Khan Academy
1. v = v 0 + a t. 2. Δ x = ( v + v 0 2) t. 3. Δ x = v 0 t + 1 2 a t 2. 4. v 2 = v 0 2 + 2 a Δ x. Since the kinematic formulas are only accurate if the acceleration is constant during the time interval considered, we have to be careful to not use them when the acceleration is changing. Also, the kinematic formulas assume all variables are ...
Mechanisms underlying nystagmus
Mechanisms underlying nystagmus. In health, there are three main control mechanisms for maintaining steady gaze—fixation; the vestibulo-ocular reflex; and a gaze-holding system (the neural integrator), which operates whenever the eyes are required to hold an eccentric gaze position 1, 2, 3 . Failure of any of these control systems will bring ...

Visual motion perception facilitates the detection of facial and bodily cues important for socio-emotional communication . Motion discrimination is impaired in both SZ (reviewed in 13) and ASD (14-16). Despite their shared characteristics, the neural mechanisms underlying FER and motion deficits in SZ and ASD are poorly understood.
Lesson Video: Applications of Derivatives on Rectilinear Motion
In this video, we'll learn how to apply procedures for finding derivatives to problems involving motion in a straight line. We'll begin by recapping the methods for differentiating polynomial functions in 𝑥 and the chain rule before considering how differentiation links to motion along a straight line. We'll then look at a variety of ...

Side to side (horizontal nystagmus). Up and down (vertical nystagmus). In a circle (rotary or torsional nystagmus). The movements can follow different patterns. Your eyes may: Drift in one direction and then jerk in the opposite direction to correct (jerk nystagmus). Drift back and forth in a steady, pendulum-like motion (pendular …

Example 6.1 Circular Motion Kinematics. A particle is moving in a circle of radius R . At t = 0, it is located on the x -axis. The angle the particle makes with the positive x -axis is given by θ(t) = At3 − Bt, where A and B are positive constants. Determine (a) the velocity vector, and (b) the acceleration vector.

Dysdiadochokinesia
Dysdiadochokinesia (diadochokinesia) is the inability to perform rapid alternating muscle movements. These can be quick and synchronous and can include pronation/supination, fast finger tapping, opening and closing of the fists, and foot tapping. It is an essential component to evaluate in patients suspected of having a cerebellar …

$begingroup$ @JonathanRSwift I notice that the speed of the slider is not constant (it appears to slide back faster than when sliding forward). Is it the animation that makes it look like that, or is that the actual behavior of the slider? - if the latter is it …
16.6 Uniform Circular Motion and Simple Harmonic Motion
There is an easy way to produce simple harmonic motion by using uniform circular motion. Figure 16.18 shows one way of using this method. A ball is attached to a uniformly rotating vertical turntable, and its shadow is projected on the floor as shown. The shadow undergoes simple harmonic motion.

In this explainer, we will learn how to apply derivatives to problems of motion in a straight line. The position of a particle in rectilinear motion can be described as a coordinate on the motion axis, 𝑥 ( 𝑡). It can also be expressed with respect to the particle's position at a given time; this is called the displacement of the particle.
Oscillatory Motion: Definition, Examples, and Equation
Oscillatory motion is a back-and-forth motion of an object about an equilibrium position. Such motion is possible only when a restoring force or torque acts on the object. The force or torque restores the object to its equilibrium position no matter in which direction it is displaced. Oscillatory motion is essential to study real-life …

This differential heating gives rise to pressure differences and, consequently, to the pressure gradient force that compels air to move. Ultimately, as we saw earlier, the moving air redistributes heat from areas of surplus to areas of deficit. Remember the vertical motion of air at High and Low pressure centers described in the ...
