clocks, engines, motors, things run by engines or motors and anything else that needs to convert something turning at one speed to turn at another speed.
Gears are used to make pieces of items or objects rotate. They are used in a majority of machines available.
Clocks and watches have internal gears. Bicycles and can openers have external gears.
Some objects that contain electromagnets are doorbells, speakers, printers, and calculaters
neon lights.
There are many objects in the world that contain carbon. Some items are seashells, pencils, fabrics, wood, carbonated sodas, and water.
Two circular objects of different sizes that rotate together is a wheel and axle. Inclined plane wrapped around a central cylinder or bar to form a spiral is a screw.
Objects that contain iron, nickel, or cobalt are attracted to a magnet.
gear or gears
Examples of objects that contain mechanisms include watches, clocks, car engines, bicycles, and vending machines. These objects have moving parts that work together to perform a specific function or task.
You can attract objects that contain iron by using a magnet, as iron is a magnetic material. When you bring a magnet near objects containing iron, the magnetic force will cause them to be attracted to the magnet.
A fishing rod itself does not have gears; it is a simple tool used for casting and retrieving fishing line. However, fishing reels, which are often mounted on fishing rods, do contain gears that help in winding the line and controlling the drag. These gears assist in managing the tension when reeling in fish. Therefore, while the rod doesn't have gears, the accompanying reel does.
Yes, cold objects contain heat, but less heat compared to warmer objects. Heat is a form of energy present in all objects, and temperature is a measure of the average kinetic energy of the particles in an object. Even objects at cold temperatures have particles that are moving, albeit slower, and thus contain some heat energy.
