  1. Sources of error for lab

    Hey! So I need help coming up with a source error for this lab I did. We rolled a car down a wooden board and timed the cart rolling down at different distances on the board. So far I have errors dealing with friction, the stopwatches, and the wooden board

  2. Sources of error for lab

    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)

  3. chemistry

    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.
