Ascientist measures a substance to be 0.6 grams. calculate the percent of error in the measurement.

Percent error is an expression that is used as a tool for determining the precision of your calculations. It is calculated by the absolute value of the difference of experimental and theoretical values over the theoretical values multiplied by 100%. Hope this helps.

Work done = force ×distancebut force = mass ×gravityand gravity = 10m\s force = 2×10 = 20 work done = 20×3 = 60 joules
