* 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.
Acceleration is the rate at which velocity (speed) is changing. If an object is moving with a constant velocity, then its acceleration is zero, since the velocity never changes.But imagine a car going along at 30 mph (miles per hour).When we check the speed one second later, we find the speed is now 32 mph. So in that one second, the speed increased by 2 mph.ut imagine a car going along at 30 mph (miles per hour). When we check the speed one second later, we find the speed is now 32 mph.
