What is Frames: Definition and 630 Discussions

Dropped Frames is a multi-album project by American musician Mike Shinoda, currently consisting of three volumes. Dropped Frames, Vol. 1 was released on July 10, 2020, with subsequent volumes following on July 31 and September 18 of the same year. The project was composed interactively with fans on Shinoda's Twitch channel. All three albums were distributed via Kenji Kobayashi Productions, Shinoda's own company capitally related to Machine Shop co. With the exception of the opening track of volume 1, "Open Door", tracks on Dropped Frames are primarily instrumental.

    Question about rotating frames

    In flat spacetime, if you are at rest in a rotating frame, how would you be able to detect that rotation? For instance, on a small planet surrounded by nothing, how can a reference frame that rotates at the angular velocity of the planet be declared noninertial? Thanks for any replies.

    Energy of a photon in different frames.

    Just a quick question here, that I've been having a bit of trouble figuring out: How do you calculate the energy of a photon in a frame if you know the energy of the photon in another frame as well as the relative velocities of the two frames? Thanks a lot.

    What Happens to Mass During the Annihilation of an Electron-Positron Pair?

    After a dispute on the nature of kinetic energy on a previous topic, a new question has arised. If kinetic energy is different for each reference frame, then what happens with mass, considering the mass-energy equation?

    Frames of reference/vectors question.

    The captain of a boat wants to travel directly across a river that flows due east with a speed of 1.48 m/s. He starts from the south bank of the river and wants to reach the north bank by traveling straight across the river. The boat has a speed of 5.64 m/s with respect to the water. What...

    Conservation of Energy in different inertial frames

    today my dynamics lecturer illustrated a situation to us where energy did not appear to be conserved. The situation involves observing the motion of a mass sliding down a slope, height 'h' above the ground from rest initially in the rest frame, we see; initially, PE = mgh KE = 0...

    Relativity in rotating frames

    Suppose there is an inertial frame S in which there exists some object A at rest, located at (x,y,z)=(10^8,0,0). Now consider the non-inertial frame S' whose axes are coincident with those of S at t=0, but which is rotating about the common z-axis with constant angular frequency w. If S' has a...

    Does Lorentz Force Change in Moving Frames?

    Consider a magnetic field with a charge at rest in inertial frame S. From this reference point the particle is not moving wrt the magnetic field and will not experience a Lorentz force. Now consider a frame S' moving wrt S at a constant speed. An observer in this frame would see the charge...

    Evidence for preferred frames?

    Kinetic energy in frames of reference

    i was just reading, and i saw this question, and i don't know how to explain it... how can you describe why when two things go at a velocity v, and one of them accelerates to 2v, the KE gain w/ respect to the Earth and the other object are different, but the work done is constant? i just...

    Reference frames in relativity

    why is it that when two events occur simultaneosuly at separated points on the x-axis of reference fram S, the observer moving in the positive X direction sees the event withe largest x coordinate first shouldnt it be the smallest?

    Frames of reference & Inertial frames

    i've just started studying these but unfortunatley I've been unable to get my hands on the textbook, and my lecturer is... not that great :frown: Could somebody explain what these are to me? I have little to no idea about them as of now... maybe a few sample questions too? That would be a...

    Is a Skydiver at Terminal Velocity an Inertial Reference Frame?

    1) Which object provides an inertial frame of reference? a. the tip of the moving second hand of a clock b. a rock thrown vertically upward c. a pendulum swinging with no air resistance d. a skydiver falling at terminal velocity At first I thought c might be correct, but now I am...

    Accelerating Frames: Apparent Weight of Crate at Equator

    Hello all! I have a question on acclerating frames. The apparent weight of an object in an elevator that is accelerating upward is m(g+a), where g is gravity and a is the acceleration of the elevator. In my textbook they give an example of a crate placed on a scale at the equator. They want...

    Special relativity and frames of reference

    I have learned that objects moving at high velocity experience time dilation, among other things, and that there is no ultimate frame of reference in the universe. If this is so...say two galaxies pass by each other at near the speed of light...in which one would time be moving slower? There's...

    Understanding Constant Velocity and Acceleration in Frictionless Environments

    Your standard first-post-pleading-for-help here :) This doesn't make sense: Say you've got a setup like in picture 1 (floor is frictionless) If the F readout on the scale is 18N, and the box is 5kg and F=ma, then 18N/5kg = 3.6m/s^2 = a, right? Okay... Now, if the velocity is...

    How Do We Determine Proper Inertial Frames of Reference?

    how do you determine if something is a proper inertial frame of reference? the Earth is but a car isnt? you can feel a car accelerate, even though you are in it, but you can't feel the Earth accelerate as it changes directions in its orbit.. is there a poitn after which you don't feel...

    Reference Frames: Can an Observer Know He is Accelerating?

    hi folks! I have a question which had been haunting me for quite some time... can an observer sitting in a accelerating reference frame deduce that he is accelerating without establishing any contact with the outside world( i am alluding to outside the frame ambience)?

    Identity and Reference Frames

    Is it possible to define one's identity (i.e. answer the question "Who are you?") without resorting to some sort of reference frame (e.g. "I am the son of so and so"), and if so, how? And for that matter, is there anything at all out there, which can be defined without a raference frame? I...

    Understanding Special Relativity: Counter Rotating Frames in Motion

Someone proposed a scenario where there were two rocket ships that would travel at constant speed along a circle in opposite directions. They would pass each other twice per revolution...

    Inertial reference frames

    I can make a local inertial reference frame in a gravitational field by creating a frame that is small but close to the source of curvature of space-time. Alternatively I can make a local inertial reference frame by creating a frame that is large but a long distance from the source of curvature...

    Question about frames of reference and clocks

    Hey everybody, this is my first post! :biggrin: I've always had a problem understanding why, if a space-explorer left on a ship, traveled at nearly the speed of light for a while, and then came back to earth, he might have only aged a few months whereas the people of Earth would have aged...

    Running 3 Miles: The Staggering Implications

    Moving in Frames?? okay, so let's say I ran 3 miles. At one point, I must have been halfway between start and finish right? From the halfway point, I must have existed halfway from there and the remaining 1.5 miles also. And halfway between THAT point and the finish. Then halfway from THAT...

    Permittivity in inertial reference frames

    Suppose 2 inertial frames with relative relativistic velocities. To discuss phenomena in other frame, we need to use Lorentz Transform for length and time. I got question: do we have to also use LT to talk about permittivity and permeability of other IRF? This seems strange. Permittivity has...

    Attention Paid To Accelerating Reference Frames Overthrows SR

    1. Let clock A and clock B be of identical construction, and let them both not be subjected to any force. Let them be at rest with respect to each other. Thus, the relative velocity v is equal to zero. Therefore, using Newtonian mechanics or SR, the clocks tick at the same rate. For the...

    Radioactive decay in relativistic frames

    Frames of Motion: Angle, Speed & River Flow
