### How do I define the initial jerk and yank of a cylinder subjected to impact of a rigid body at it's base?

I am trying to solve an axisymmetric longitudinal wave propagation problem during the impact (collision) of a rigid body and the base of a cylinder. On one end the cylinder is rigidly bound to the ...

About jounce (snap). So change in acceleration is know as jerk, so like this is still imaginable but what is change in jerk, like can you give some real life example where that is happening.

### The jerk that happens when going from linear to circular motion [closed]

Im trying to calculate the force applied to the end of a beam when going from a linear motion to a circular motion. I have a tractor with a beam of each side with a length "L" The tractor is ...

### Gravitational acceleration in my acceleration data (IMU)

I am trying to do gait analysis and remove gravitational acceleration ($9,81 m/s^2$) from my data. I have used IMU (on the patient's lower back) to record acceleration, angular velocity and roll/pitch/...

### Vertical movement of an object with gravitational acceleration not constant

I don't know how to start, but i will give you some context: Let's say that we have a body that we want to vertically propel at a distance of $h_f=10$ km of it's original spot considering that the ... 57 views

### Areas of physics and physical scenarios where jerk comes up [duplicate]

I am a high-schooler and I learnt that the third derivative of displacement with respect to time$\left(\frac{d^3s}{dt^3}\right)$ is known as jerk. I am curious to know where does this come up in ... 234 views

### Is The Third Time Derivative of Position Relative, and if it is, Can it be represented in 6 Dimensions?

Einstein’s Theory of Special Relativity only applied to objects at constant velocities. This could be represented in a four dimensional Minkowski Space. From what I understand, Einstein compared ...

### Is impulsive tension called jerk? [closed]

Jerk is derivative of acceleration, is impulsive tension also the same. Or there is nothing like impulsive tension

### Name for the set Displacement, Velocity, Acceleration, etc

Is there a name for the set Displacement, Velocity, Acceleration, Jerk, etc? The only name I can think of is 'Derivatives of displacement (wrt time)' which is rather long.

### Why don't we define time derivative of acceleration? [duplicate]

When we started the study of kinematics we defined position and its change with respect to time. After that we defined time derivative of velocity which gave us acceleration. These 3 concepts really ...

### Upper limits for jerk and higher derivatives in physics

Is there an upper limit for jerk in physics? What about higher derivatives? A consequence of special relativity is that no material body can reach or exceed the speed of light in vacuum (due to ...

### What is $mass \cdot jerk$, or yank?

So if Momentum is $m \cdot v$, Force is $m \cdot a$, and Jerk is $\frac{\Delta a}{\Delta t}$ what is $m \cdot j$? I've read that the name for this is yank, but I'm curious as to what it is ...

### Does the Jerk (derivative of acceleration) play a significant role in relativity?

In particular, I'm thinking of spaghettification that occurs as an object falls into a black hole (as an extreme example). But what about tidal forces like the tidal heating taking place on Jovian ...

### Applying energy and momentum conservation to the problem of pulling a bent carpet at a constant speed

Consider this system. A long, thin, pliable carpet is laid on a floor. One end of the carpet is bent back and then pulled backwards with constant speed $v$, just above the part of the carpet ...

### Instantaneous changes in acceleration

These are very simple looking graphs. What I don’t understand is (I’m talking of the highlighted text in blue at the bottom), it says such instantaneous changes in acceleration can not occur in ...

### If the jerk is 2, then acceleration is 2t, velocity is $t^2$ and distance is $t^{3}/3$? [closed]

Are my graphs and equations right? I just began learning about these..
