* A lumen is the same as Lux and is what many modern light meters will calculate their measurement in. The next step is to calculate the number of watts. One lumen is = 0.001496 watts. This is pretty simple, after you have your total number of lumens from step 2.
Quick Answer. The formula for speed is s = d/t, where s equals the speed, d is the distance covered and t is the time it took to cover the distance. The formula for finding the instantaneous speed at a specific point is found by taking the derivative of the speed equation. Continue Reading.
In a physics equation, given a constant acceleration and the change in velocity of an object, you can figure out both the time involved and the distance traveled. For instance, imagine youâre a drag racer. Your acceleration is 26.6 meters per second 2, and your final speed is 146.3 meters per second. Now find the total distance traveled. Got you, huh?
