Impetus describes the kind of force that encourages an action (the impetus behind the project) or the momentum of an action already begun (the meetings only gave impetus to the rumors of a merger).
Materials Needed: The box from the last experiment; a ruler that measures centimeters. Procedure: Measure each side of the box in centimeters. Use the formula for the volume of a box shaped object (V = L x W x H ) to calculate the volume of this box in cubic centimeters. What Happened: Each side was 10 cm long. When you plug the numbers into the formula and do the math, you get:
When measuring a small liquid volume, such as a dosage of cough medicine, the best unit to use is milliliters or ounces. A slightly larger volume, like the amount of flour or sugar needed to make cookie dough, would be measured using cups. A liquid volume of this size, like heavy cream, would be measured using pints, milliliters, or liters. The volume of a bigger amount, like a bottle of apple juice or soda pop, can be measured using liters and quarts. A really big liquid volume, like an aquarium or swimming pool, would be measured in gallons or liters.
