What is the definition of speed?

Question

Can someone help me here if speed=ditsance traveled in a given amount of time then wouldnt the speed of light be expotential because it travels sphericaly from its point of origin and if that were true shouldnt Einsteins special theroy of relativity be energy = mass times the spherical velocity of light instead of square maybe I am just really confused is it total distance travled or distance between point a and point b only??? billy buttface please no answer

Answer 1

Speed is distance travelled by time taken. Your confusion arises because you take the entire wavefront. In that case the increase of radius is the distance travelled.

And if I circumnavigate the globe and reach the starting point, it doesnt imply my speed is zero, but rather Circumference of the earth/time taken

Answer 2

Speed would be distance from Point A to Point B. It's the accepted way to measure speed. Otherwise there would be too many variables measuring different things such as sound, light, a bowling ball.

Answer 3

Speed is a scalar. Velocity is a vector.
If you were travelling at a constant speed around a circular track, your velocity would be changing because your direction is changing.

E=MCsquared is not Einsteins theory of relativity (at least not as I know it). It is a mass/energy theorem.

Answer 4

Light travels in straight line. The common definition holds true....distance divided by time

Answer 5

with a view to respond to your very interesting question,I´m going to attempt provide to you an quite relativist soluttion: Mr.Einstein advised: E=M C^2;C=mild velocity;then; C=(E/M)^a million/2.in case you comprehend capability generate for The propelent element,and the mass ate up for propelent to have this capability , you comprehend eassily the value obtainned.

Answer 6

your question doesnt make any sence to me. but im pretty sure youre making it more compicated than it really is
