- 1.
Which other vehicle works on forced air like a hovercraft?
- A.
Motorcycle
- B.
Car
- C.
Skateboard
- D.
Helicopter
Correct Answer
D. HelicopterExplanation
A helicopter is the correct answer because, like a hovercraft, it uses forced air to generate lift and stay airborne. Both vehicles rely on the principle of creating a cushion of air beneath them to reduce friction and allow for smooth movement. While motorcycles, cars, and skateboards do not use forced air for propulsion or lift, helicopters and hovercrafts share this common feature in their design and operation.Rate this question:

A rudder is used for what?
- A.
Increase speed
- B.
To change the direction
- C.
To balance the craft
- D.
To power the engine
Correct Answer
B. To change the directionExplanation
A rudder is used to change the direction of a craft. It is a control surface that is typically located at the rear of the craft, and it can be turned left or right to steer the craft in the desired direction. By deflecting the rudder, the flow of water or air is redirected, causing the craft to turn. This is an important function for maneuvering and navigating a craft, whether it is a boat, airplane, or other type of vehicle.Rate this question:

Which is NOT a part of a hovercraft?
- A.
Skirt
- B.
Propeller
- C.
Wires
- D.
Wheels
Correct Answer
D. WheelsExplanation
A hovercraft is a vehicle that is designed to travel over both land and water by creating a cushion of air between the vehicle and the surface. It is propelled by a propeller and is supported by a skirt, which helps to trap the air and create the cushion. Wires are not typically a part of a hovercraft's design. Wheels, on the other hand, are not present in a hovercraft as it does not rely on wheels for movement or support.Rate this question:

Hovercrafts can be used on land, water, and sand.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Hovercrafts are vehicles that are designed to travel over various terrains, including land, water, and sand. They are equipped with a cushion of air that allows them to glide smoothly over these surfaces without friction. This makes hovercrafts versatile and capable of navigating different environments, making the statement "Hovercrafts can be used on land, water, and sand" true.Rate this question:

A series circuit will work even when one light in the series burns out.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
In a series circuit, the components are connected in a single path, so if one light bulb burns out, it creates an open circuit and interrupts the flow of current. As a result, the other lights in the series will also not work because the circuit is broken. Therefore, the statement that a series circuit will work even when one light in the series burns out is false.Rate this question:

Hovercrafts are much more difficult to control. This is because they lack?
- A.
Friction
- B.
Gravity
- C.
Weight
- D.
Speed
Correct Answer
A. FrictionExplanation
Hovercrafts are much more difficult to control because they lack friction. Friction is the force that opposes motion between two surfaces in contact. In the case of hovercrafts, they are designed to float on a cushion of air, which reduces the friction between the craft and the ground or water. This lack of friction makes it challenging to control the hovercraft's movement and direction, as there is less resistance to counteract the forces acting on it.Rate this question:

If a hovercraft is not balanced, then it will likely _________ once it gets up to speed.
- A.
Turn the wrong way
- B.
Hover higher
- C.
Flip
- D.
Spin
Correct Answer
C. FlipExplanation
If a hovercraft is not balanced, it means that its weight distribution is uneven. This imbalance can cause the hovercraft to become unstable and lose control once it starts moving at high speeds. As a result, the hovercraft is likely to flip over due to the lack of balance, making "Flip" the correct answer.Rate this question:

Hovercrafts are much more difficult to control when driving. This is because they lack which factor?
- A.
Weight
- B.
Speed
- C.
Gravity
- D.
Friction
Correct Answer
D. FrictionExplanation
Hovercrafts are much more difficult to control when driving because they lack friction. Friction is the force that opposes motion when two surfaces are in contact. In the case of hovercrafts, they are designed to hover above the ground or water, which means there is minimal contact and therefore minimal friction. Without friction, it becomes challenging to control the movement and direction of the hovercraft, making it more difficult to drive.Rate this question:

What is the part called that is spun by the motor and creates forced air?
- A.
Fan
- B.
Propeller
- C.
Wing
- D.
Blade
Correct Answer
B. PropellerExplanation
A propeller is the part that is spun by the motor and creates forced air. It is commonly used in various applications such as airplanes, helicopters, and fans. The rotating motion of the propeller blades generates a flow of air or fluid, resulting in a propulsion force. Unlike a fan, which is typically used for circulating air in a room, a propeller is specifically designed for generating thrust and moving through a medium like air or water. Therefore, the correct answer is propeller.Rate this question:

What is the Hovercraft used for?
- A.
For war by the Armies
- B.
Fishing
- C.
Many people use it for fun
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The hovercraft is a versatile vehicle that can be used for various purposes. It is commonly used by armies for military operations, as it can easily traverse different terrains and provide swift transportation. Additionally, hovercrafts are also utilized in the fishing industry, as they can access shallow waters and navigate through difficult areas. Moreover, many individuals enjoy using hovercrafts for recreational purposes, such as racing or leisurely rides. Therefore, the correct answer is "All of the above" as the hovercraft can be used for war, fishing, and for fun by different groups of people.Rate this question:
