What is a land vehicle? What directions can it move in?
A land vehicle is a motorized vehicle used for transportation on land. It can move forward, backward, and can steer left or right.

What is an air vehicle? What directions can it move in?
An air vehicle is an aircraft designed for air travel, such as airplanes and helicopters. It can move forward, ascend, descend, and turn left or right.

Which directions can helicopters fly? What directions can’t they fly and/or rotate?
Helicopters can fly forward, backward, ascend, and descend. They can also rotate clockwise and counterclockwise. However, they cannot move directly sideways without rotating.

Which directions can/can't planes fly?
Planes can fly forward, ascend, descend, and turn left or right. They cannot move directly backward or sideways without special maneuvers.

Can a helicopter fly sideways? What directions can it fly in?
Helicopters can hover and rotate, allowing them to move sideways indirectly, but they cannot move directly sideways without rotating.

Name parts of the control panel in a car. Explain their functions.
Common parts include the steering wheel (controls direction), accelerator (increases speed), brake pedal (slows down/stops the car), and gear shift (controls speed and direction).

How to use a remote control transmitter for a model plane/model car?
The remote control transmitter sends signals to the model's receiver. It typically has joysticks or buttons to control movements like throttle, steering, and other functions based on the model's design.

How can you control the movement of a car?
Car movement is controlled by the driver using the steering wheel for direction, accelerator for speed, brake pedal for slowing down, and gears for controlling speed and power.

What directions do you know in English?
Directions in English include forward, backward, left, right, up, down, clockwise, and counterclockwise.

What words are used to describe movement?
Words like walk, run, crawl, jump, slide, spin, and twist are used to describe movement.

What is the difference in robot arm and human arm movements?
Robot arms can be programmed for precise movements, while human arms have more complex and adaptable motions due to joints and muscles.

How does the heating system work? What are the parts of a typical house heating system? How does water move in this system?
A heating system uses a furnace or boiler to generate heat, which is distributed through ducts or pipes to radiators or vents in different rooms. Water moves through pipes and radiators, heated by the boiler, and then returns to be reheated.

What is a valve?
A valve is a device used to regulate, direct, or control the flow of a fluid (liquid or gas) by opening, closing, or partially obstructing various passageways.

What is an inlet?
An inlet is an opening or entrance, especially one in a wall or other surface allowing air or liquid to enter a space or container.

How does the car cooling system work?
The car cooling system circulates coolant (usually a mixture of water and antifreeze) through the engine and radiator. The coolant absorbs heat from the engine and releases it into the air passing through the radiator, cooling the engine.

What parts does a car cooling system have?
A car cooling system includes a radiator, water pump, thermostat, hoses, and a fan. These components work together to regulate the engine temperature.

What parts of a water-cooling system do you know?
A water-cooling system typically includes a water block (for the component being cooled), a pump, tubing, a radiator, fans, and a reservoir.

What is a solar panel and how does it work?
A solar panel is a device that converts sunlight into electricity. It consists of multiple solar cells made of semiconductor materials. When sunlight hits the cells, it creates an electric current, generating electricity.

Where and why are heating/cooling systems used?
Heating systems are used in buildings, homes, and vehicles to provide warmth in cold weather. Cooling systems are used to maintain comfortable temperatures indoors, especially during hot weather, in buildings and vehicles.

What is an electrical circuit? What are its parts?
An electrical circuit is a closed loop through which an electric current flows. It consists of components like resistors, capacitors, inductors, and switches, connected by conductive wires, allowing the flow of electricity.
