### Application of Coriolis force and centripetal acceleration

Consider a slider capable of sliding on a rod. The rod has a constant angular velocity of $\omega$, and the slider is moving up the rod with a velocity $v$ and acceleration $a$ with respect to the bar....

### Circular motion with tangential acceleration limited by grip

Let's suppose I'm running in a circle. The maximum acceleration is limited by a value $\mu$: $v^2/R = \mu*g$ So, if I'm running in that circle at a speed lower than the max speed (the lateral ...

### Throwing darts in a rocket ship

Far from major gravitational sources... A man is standing throwing darts at a dartboard in a rocket ship. The thrust is upwards so he feels almost like he would on Earth but the G-force is slightly ...

### In what sense do we say that the Earth surface is almost inertial in Newtonian mechanics?

From what I understand, inertial frames are the ones in which the momentum of every particle in the universe gets well accounted for. Like if there's any particle losing momentum, another particle ...

### Can velocity change without any component of acceleration in opposite direction of motion?

If a truck of mass 100kg is moving with some velocity say 10m/s ( pls assume friction is negligible but still truck is moving)when suddenly an object of mass 10kg falls on it from above and ...

### Working of Capacitive Accelerometer

I've been studying about capacitive accelerometers, and basically how they work is by detecting the change in capacitance or as a result of change in the distance between the conductive plates, small ...

### A $2.0$ ton truck provides an acceleration of $3.0$ ft/s^2 to a $5.0$ ton trailer [closed]

I am doing this problem for practice, and I am not sure what I am doing wrong. A $2.0$-ton truck provides an acceleration of $3.0 \frac{ft}{s^2}$ to a $5.0$-ton trailer. If the truck exerts the same ...

### Is there an upper bound on acceleration? [duplicate]

We know from the Theory of Relativity that there is an upper bound on velocity, namely the speed of light $c=2.99792458\cdot 10^8\frac{m}{s}$. Is there an analogous upper bound on acceleration? I don'...

### Experiment of an accelerated charge’s radiation in General Relativity [duplicate]

I have seen a video saying a stationary (from our frame) charge should radiate, because is accelerated, the falling charges are the ones with no acceleration. But he says we cannot test it due some ...

### Is an accelerating velocity the same as an identical non-accelerating velocity?

I’m referring to an instant in time where the velocities of two different particles are identical. One particle experiences a force and the other does not. I think their states of motion are different ...

### Did we just misunderstand gravity?

Einstein told us that a spring balance under free fall shows zero deflection and thus derived that gravity is a curvature in the fabric of spacetime and all those stuffs. Now let's assume we have a ...

### Acceleration in a space without friction [closed]

If an object is accelerated by one point (say, at 09:00 objected is forced) after no force is applied to the object in a space without friction, does it move forever...?

### Would the jerk of this rocket be constant?

I was working on this interesting problem I came up with for a couple hours and got stuck - decided to ask here. A rocketship with is accelerating upward with constant thrust. Ignoring air resistance ...

### Detecting (absolute) acceleration in an almost empty Newtonian world

Imagine we've got two massless particles in an otherwise empty Newtonian world, both at the same position, with zero velocity in t0. One is without acceleration, but the other has a constant ...

### The motion of an object moving up and down through an infinite plane

Consider an infinitely large plane which exerts gravity onto a point mass with mass $m$ and located at height $h_0$. The point mass moves perpendicularly through the plane without undergoing any ...

### Why would an orbiting electron lose energy?

Ernest Rutherford proposed that the electrons were orbiting around the nucleus just like planets orbiting around the sun. However, this simple picture defied the laws of physics. Electrons revolving ...

### Newtonian Mechanics- A train with five wagons [closed]

Let me post a question from a school textbook sent to me by a friend of mine. The book has no answer scheme and googling the question is not particularly helpful because the answers seem to vary ...

### What if a body Accelerate non-uniformly?

As we generally deals with inertial frame of reference and non inertia frame of reference, but what if a body is non-uniformly Accelerate What do we do to make newtons laws still valid in later frame ...

### Is non-tangential force produce angular acceleration

As torque is the only reason for angular acceleration but... When radial force act on a body it automatically become zero as it passes through center And only thing left is tangential force which is ...

### Why masses connected by via a string have same accleration?

The system is in equilibrium, and the following discussion occurs after spring-1 is cut. Now, as soon as spring-1 is cut it is clear that the spring force acting one M due to spring-1,will be zero ...

### Why an electron bound to a nucleus does not emit photons when accelerated?

I think electrically neutral materials do not generate electromagnetic radiation/photons when accelerated, but I might be wrong. If I am correct though, why is it that accelerated ions generate ...

### Confusion in law of interaction [closed]

Suppose that two particles $P_1$ and $P_2$ interact with each other and that $P_2$ induces an instantaneous acceleration $a_{12}$ in $P_1$, while $P_1$ induces an instantaneous acceleration $a_{21}$ ...
