Make A Spacetime Diagram And Draw Worldlines For Each Of The Following Situations

It intersects the. This represents the motion of a beam of light.

Spacetime Wikipedia

C earth relays signal towards ship.

Make a spacetime diagram and draw worldlines for each of the following situations. The vertical axis represents the worldline of a stationary particle called observer 1. Space is different for different observers. Spacetime is the same for everyone.

The horizontal line is considered the space axis of observer 1. The space time diagrams in the earth and rocket ship frames are shown above. Our observer measures the coordinates of an event and locates them on the graph.

Astr 1401 chapter 8. Make a spacetime diagram and draw a worldline for each of the following situations. The second in a series on special and general relativity.

Also note that 45 yields 53. Time is different for different observers. Time runs slower on the surface of the sun than on the earth.

To make things simple time will be represented in units of 1 s and distance in light seconds this will make the gradient of a body travelling at the speed of light 1 you could also use time in years and distance in light years. Worldlines at low speed. We agree to allocate to each observer say s a graph with vertical and horizontal axes.

Spacetime diagrams are a standard tool for under standing the implications of special relativity. An introduction to spacetime diagrams which are a valuable tool used to understand special relativity. A person driving by at a constant velocity of 100 kmhr d.

Distance on a spacetime diagram. We may certainly rephrase this difficulty in the following way. Draw a timelike line.

What is the equivalence principle. Drawing a spacetime diagram draw horizontal and vertical axes. 2 and sends signal to earth.

Draw a diagonal line at 45. Make a spacetime diagram and draw worldlines for each of the following situations on the same drawing. And d ship receives relay.

What is a hyperspace. Let us know what you think of these. The first thing to realise is that in a space time diagram time is represented on the y axis.

Person sitting still in a chair b. Consider a spaceship on a long trip with a constant acceleration of 1 g. But now we draw on the spacetime diagram for s.

Label which worldline is which. A person driving by at a constant velocity of 50 kmhr c. E mc2 if you observe someone moving by you youll see their time running slow.

A space time diagram displays invariant physical content geomet rically making it straightforward to determine what is happening in each reference frame not merely the one in which the diagram is drawn. Gravity is curvature of spacetime. Note that each gridline corresponds to c h3 in the earth frame and c h5 in the rocket ship frame.
