Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity). When unspecified, "time dilation" usually refers to the effect due to velocity.
12 wrz 2022 · Definition: Time Dilation. Time dilation is the lengthening of the time interval between two events for an observer in an inertial frame that is moving with respect to the rest frame of the events (in which the events occur at the same location).
16 lut 2022 · In his theory of general relativity, Einstein predicted something called time dilation: the notion that two clocks under two different gravitational pulls will always tick at different speeds.
24 wrz 2016 · Suppose that we want to compute the total time dilation for a clock located in an orbiting satellite relative to the clock in our cell phone on the ground. Consider two different approaches below. Use special relativity and compute time contraction due to the relative velocity.
Explain how time intervals can be measured differently in different reference frames. Describe how to distinguish a proper time interval from a dilated time interval. Describe the significance of the muon experiment. Explain why the twin paradox is not a contradiction. Calculate time dilation given the speed of an object in a given frame.
9 sty 2015 · For each small time step $\Delta t$, measure it according to local time, dilate accordingly, and update the display. Is there any reason why this watch wouldn't work, given my near-zero acceleration assumption? And can anyone think of a design that would work even with acceleration?
Here's a primitive clock: a blob of light bouncing back and forth between two fixed mirrors. If the clock is moving relative to us, the light must go further on a zigzag path—but its speed must be the same, so it takes longer, and the clock runs slow. It's all fully explained in this lecture!
