ACCELEROMETER WRITE UP :)

For the first experiment we chose to drive around with the accelerometer. Emily was driving while Anna held the accelerometer. As Emily accelerated, the cork moved to the front on the jar in the direction of the acceleration. We then came to an immediate stop, which caused the cork to move back to the middle of the jar. This happened because the water inside the jar is more dense than the cork. Knowing this, we realized the water had more inertia then the cork thus being able to stay at rest (Newton's 1st Law). As both tried to remain at rest, the water was stronger at keeping this position, therefore causing the cork to move towards the acceleration.

For the second experiment, Emily held the accelerometer in her hands while she spun around in a circle multiple times. What we noticed was the cork and water moved forward in the direction in which she was spinning, following her hrough the revolutions. The cork was more relevant in showing the direction of the acceleration because the water is more dense then the cork thus having more inertia. This caused the cork to be pushed farther than the water as the water remained at rest when the cork began in motion because a force of tension and gravity were acted on it.

For the last experiment, Anna rolled the accelerometer down the top of an exercise chair. This chair had a large incline, and resembles a very steep ramp. As anna rolled the accelerometer down the ramp, the cork went forward, in the direction of the acceleration. As the accelerometer progressed down the ramp, the acceleration increased. The cork went in the forward direction because the water pushed the cork forward, the water had more inertia to stay at rest. The cork had less inertia than the water and was therefore pushed forward. The direction of the acceleration and the cork are related in which the cork goes in the same direction as the accerleration.
