The definition of energy is the ability to do work. All energy is put into either kinetic energy or potential energy. When something is moving, it uses kinetic energy to keep it moving. …show more content…
Aerodynamics is the way air moves around things. A car can move more efficiently when the car is rounded. Because the car is rounded, the air brushes past it making the car easy to move. If the car was squared then the air would hit the corners and edges and it wouldn’t move as efficiently. This is because when the air goes across an edged surface, it doesn’t glide over the surface. The air has to make sharp turns over the car making the drag on the car bigger. Like the cars, shapes of water bottles make a difference in water bottle-designed car’s speed. When the water bottle-designed car is built, different shaped water bottles are used to make different shaped cars. The most rounded water bottle will probably go farther because the air moves better across the rounded bottle than against the square, edged bottle.
What water bottle-designed car will travel the fastest? Knowing the 3 factors that determine which car travels the fastest, it is easier to understand the experiment. One of the factors is kinetic energy and how it pushes the water bottle car forward. Also, Newton’s third law of motion tells how the air from the balloon pushes the car forward. Aerodynamics made it easier to understand how the shape of a car affects its ability to move. All of these factors will help determine which water bottle car will travel the
