fish
the fins on fish helps it to move easily in water
boats
the engine of the boat helps it to move easily
sorry don't have a third one
Of the three, water will move easily. The others require help and therefore the use of energy.
You could save gasoline by driving your car underwater ? ? ?
Gravity underwater affects the movement of objects and organisms by making them feel lighter and more buoyant. This can cause objects to float or sink, and organisms to move more easily through the water.
objects can be moved by human or by machines
Both water and air are fluid mediums, meaning they can easily flow and move around objects. Additionally, water and air have low resistance to motion compared to solid mediums, allowing objects to move through them with relatively little effort. This property makes them ideal mediums for motion, whether for boats in water or airplanes in air.
Yes, it is generally easier to move objects in water compared to on land, because water provides buoyancy that helps support the weight of the object. Also, water has less friction compared to land surfaces, making it easier to push or pull objects in water.
Water will spill more easily, as sand is a solid it will not move around much when in a bucket, with water it will want to move all over the place.
Mechanical waves (e.g. water waves, sound waves, seismic waves) cause objects to move because the waves themselves are mechanical motion of objects. Electromagnetic waves usually do not move large visible objects, but move electrons, atoms, and molecules because they respond to the moving electric field of the wave. This can cause electric currents in the object or heating of the object.
Hydrophobic substances avoid or move away contact with water. Hydrophilic objects move toward water.
The speed at which objects travel through water depends on various factors such as the size and shape of the object, the density of the water, and any external forces acting on the object. Generally, objects move slower in water compared to in air due to the higher density and viscosity of water. Some objects, like fish and boats, can move relatively fast through water, while others, like rocks, may hardly move at all.
Water acceleration can affect the movement of objects in a fluid medium by increasing the speed at which the objects move. When water accelerates, it creates a force that can push or pull objects in the same direction, causing them to move faster or change direction. This acceleration can impact the overall flow and behavior of objects in the fluid medium.
