Inertia: An object at rest tends to stay at rest and an object in motion tends to stay in motion.
Acceleration / Force & Mass:When a force is applied to an object, it accelerates.The acceleration is in the direction of the force and proportional to it's strength, and also inversely proportional to the mass being moved.
- Inversely Proportion means that as the mass of an object gets larger, the amount of acceleration that the force is able to provide get smaller.
How We Showed It
Inertia: When the bottle was at the starting point it was at rest, but when it was shot it wasn't.
Acceleration / Force & Mass: A push caused it to accelerate toward the door.The air pressure of the alcohol's (Ethyl Alcohol) vapor pushed it. Also because there was less weight caused it to go faster.One thing to make it go faster was to put more alcohol in it.To slow it down we could of put weights on the bottle, or put less alcohol.
Action and Reaction:The action was the pressure, or force, that made the bottle move.The reaction was that the bottle move toward the door.
What We Did To The Bottles
Inside:
- The first thing we did was, put alcohol in it.
- The second thing was to shake it really good so that the alcohol inside would turn into vapor.
- Third, we placed it on the string.
- We lit the top of the bottle.(WHOOSH, it went toward the door.)
- We had to put alcohol int the bottle.
- Second, we had to shake it.
- We placed it on the string.
- Lit it at the hole. (Then it went flying towards the playground.)
