# AIR CAR BOAT - DIY kit for Students

Updated: May 1

The very first airboat to be registered in America was right here in Florida in the 1920s. Airboats were initially used as means of navigating shallow waters, like those in the Florida Everglades, so that people could fish and hunt. The air boat that runs with the help of air motion, not only this but peculiar thing is that it runs on land aswell as on water. It’s interesting! Let’s start with your amazing project!A Newton Air Car Boat demonstrates Newton’s third law of motion, namely the law of interaction: For each action, there is an equal and opposite reaction. The car does this by hurling a weight off the back, forcing itself forward. This is a demonstration of how rockets are propelled in space, ejecting something that was initially internal.(This experiment also illustrates his second law of motion:Force equals mass times acceleration.)Through the use of this Air car Boat, this activity demonstrates Newton's third law of motion—which states that every action has an equal and opposite reaction. The "Newton rocket cars" that students put together show how action/reaction works and how the mass of a moving object affects the acceleration and force of the system. Subsequently, the Newton cars provide students with an excellent analogy for how rockets work.Engineers often build models to demonstrate and study the physical laws of science as they apply in different situations and applications. Engineers who design rockets might even experiment with a small wooden car to understand Newton's third law of motion. Such a Air Car Boat must obey the laws of motion, just as a rocket must. Observing how a Air Car Boat moves forward when a small block is launched off its back is analogous to a rocket moving forward when hot gases are expelled from the back of the rocket. By studying the similarities and differences between a small model and a real-world rocket, engineers can successfully build rockets using what they learned from their experimental model demonstrations.

· Propeller: Rotates and powersa boat forward or backward

· Hull: Body of a vessel

· Keel: Main centerline (backbone) of a vesselor the extension of hull that increases stability in the water

OBSERVATION:

On connecting the battery and placing it on the plane surface you will observe that the fan blade rotates and the Air Car Boat starts moving forward. You’ll be able to get the car to move forwards and backwards. Direction the car moves will depend on what directionthe motor is spinning. If your Car moves backward,interchange +ve –ve connections.

On connecting the battery and placing it on the Water surface you will observe that the fan blade rotates and the Air Car Boat floats in water. You’ll be able to get the Air Car Boat to float forwardsand backwards. Direction the Air Car Boat will depend on what direction the motor is spinning. If your Air Car Boat floats backward, interchange +ve –ve connections.

## HOW IT WORKS:

This happens because of Newton’s third law of motion Newton's Third Law of Motion (law of reciprocal actions) states: "Every action has an equal and opposite reaction" i.e. Action and reaction are equal in magnitude and opposite in direction. Here the motion of the fan cuts the air which creates force on the back side and this force the car to move forward. Hence the car moves. A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. …

## AIR CAR BOAT ON PLANESURFACE:

In Newton’s Car, propeller works as a wing, it produces lift, but in a forward direction—a force we refer to as thrust. Its rotary motion through the air creates a difference in air pressure between the front and back surfaces of its blades.In order for a propeller blade to spin, it usually needs the help of an engine.A vessel's propeller works by thrusting a column of water away from the main body of the ship, thereby producing a reactive force that moves the boat forward. ...propeller blades work in water much like fan blades work in air. The main thrust bearing is located at the forward end of the main shaft within the gear casing.

How does a propeller producethrust?

Just as wings produce the force of lift (perpendicular to the wing) to lift the airplane through the air, airplane propellers produce a force of thrust (perpendicular to the propeller blades) to propel the aircraft through the air. The rotating propeller of the aircraft is camberedlike a typical aerofoil.

## AIR CAR BOAT ON WATER SURFACE:

Boat PROPELLERS DEFINED. ... Usually consisting of blades, a boat prop spins around a central shaft to create dynamics similar to a rotating screw or airfoil. When blades spin, a pressure difference between the forward and rear surfacesis produced, accelerated the water behind the blade to create force.
