## What is K in SHM?

Graph of displacement against time in simple harmonic motion.

where F is force, x is displacement, and k is a positive constant.

This is exactly the same as Hooke’s Law, which states that the force F on an object at the end of a spring equals -kx, where k is the spring constant..

## What is the maximum acceleration possible?

A: You’re right that the maximum acceleration for some cars can be in the neighborhood of g, 9.8 m/s2. That means that the coefficient of friction, μ, has to be around 1 or so. (There’s no rule that it can’t be larger than 1.)

## Can the speed of a body be negative?

The ratio of distance travelled and the time taken by a body can be zero but not negative. Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities, speed cannot be negative.

## What is minimum acceleration?

The acceleration is minimum when a′(t)=0∧a″(t)>0. a′(t)=0.007812t−0.18058. a′(t)=0 for t0=23.1157s. a″(t)=0.007812>0 thus t0 is a local minimum. as the derivative a(t) is positive for t>t0 the acceleration is increasing so the minimum is also a global minimum.

## Is acceleration constant in simple harmonic motion?

Simple harmonic motion is characterized by this changing acceleration that always is directed toward the equilibrium position and is proportional to the displacement from the equilibrium position.

## Is the acceleration of a simple harmonic oscillator ever zero if so where?

Yes, the acceleration of a simple harmonic oscillator is zero at the equilibrium point where the displacement is zero.

## When a body is oscillating in simple harmonic motion is its acceleration zero at any point if so where and why?

Acceleration in SHM The acceleration also oscillates in simple harmonic motion. If you consider a mass on a spring, when the displacement is zero the acceleration is also zero, because the spring applies no force.

## What is φ in the equation?

It’s typically written using “phi,” ϕ. … In which y0 is the y position at x = 0 and t = 0, A is the amplitude, T is the period and “phi” ϕ is the phase constant. For this sinusoidal wave, the period T = 1/f for frequency (f), which is how many cycles of a wave pass over a given point per second.
