In order to use the above speed, distance & time calculator, or do such math on your own, you will need to know two out of three metrics: speed, distance, time. Even for very tiny things, like subatomic particles, the amount of energy ( E ) needed to near the speed of light poses a significant challenge to the feasibility of almost light-speed space travel. Wind speed (Knots) Label Effect on sea Effects on land; 1: Calm: Sea like a mirror: Calm. The speed of light, usually denoted by c, is a physical constant important in many areas of physics. Sound travels at 344m/s and Light travels at 3*10^8m/s.
