how would that be an error?
It was straight. It was a straight wooden board. We held up the wooden board with different objects, to increase the angle of inclination/height, and then dropped the cart down the wooden board. (Does that help)
Because certain chemicals react much faster with others, so in order for the experiment to work properly, they need to go into the mixture in a certain order.
