Q:

How does a water turbine work?

A:

Water turbines convert the motion of moving water into rotating mechanical energy by catching the water with large blades. They are important to the structure and function of hydropower plants. There are different models of water turbines, but all perform the same basic function of converting the energy of the moving water into the revolutions of a shaft.

A hydropower plant converts the energy of naturally moving water, such as a river, into usable electrical energy. In order to do this, the plant needs a machine that can transfer the motion of water into a mechanical form. The water turbine serves this purpose. A turbine is usually disc-shaped and has a number of large, curved blades for catching the water's motion. This type of model is referred to as a Francis Turbine, and it is one of the most common types of water turbines

To convert mechanical energy into electrical energy, many generators require a revolutionary force. This is why a generator is placed at the top of a shaft that connects to the water turbine. As the turbine catches the naturally moving water in its blade and rotates, the generator receives the necessary force and begins to generate electrical energy.

    How does a perpetual motion watch work?

    A:

    A perpetual, or self-winding, watch keeps itself wound using a component called a rotor which is moved by gravity when the arm swings or moves and is connected to gears that translate the movement to circular motion within the watch. These watches usually generate enough energy from movement to keep themselves running for one and a half to two days even when sitting still.

    How do seat belts work in terms of the three laws of motion?

    A:

    There are many factors concerning Newton's three laws of motion and seat belt use when a vehicle comes to a stop suddenly due to an accident. The first deals with inertia. According to HowStuffWorks, Newton put it this way: "Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it."

  • Q:

    What is the function of a turbine?

    A:

    Turbines convert the kinetic energy of a moving fluid or gas into rotational energy that can be used to drive a dynamo and generate electricity. Usually, the source of the kinetic energy is steam, although it can sometimes be water.

    How do water rockets work?

    A:

    A water rocket works because of air pressure that is builds inside a container filled with water, usually a plastic soda bottle, which is released rapidly through an opening as it tries to escape. The reaction of a water rocket is an excellent example of Newton’s third law of motion, which states that forces exist in pairs.
