What are changing direction of free moving objects such as air and water?
Changing direction of free moving objects such as air and water can be influenced by external forces like pressure gradients, temperature differentials, and the presence of obstacles or boundaries. These forces can cause the fluid to flow in different directions, creating patterns of movement.
What is a friction that acts on objects moving through a fluid called?
Drag is the friction that acts on objects moving through a fluid like air or water. It slows down the movement of the object by creating resistance in the opposite direction.
Why do objects appear different in size and shape in a container of water due to refraction?
When light passes from air into water, it changes speed and direction, causing objects to appear distorted or different in size and shape when viewed through the water. This phenomenon is called refraction.
Why does an object move when water is moving?
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.
Which force do air and water both exert on moving objects accelerating or decelerating?
Both air and water can exert a drag force on moving objects, which can cause acceleration or deceleration depending on the direction of the object's motion. This drag force is due to the resistance of the fluid (air or water) against the motion of the object, and is influenced by factors such as the object's size, shape, and speed.
What force slows down objects moving in water?
The force that slows down objects moving in water is called drag. Drag is caused by friction between the object and the water, which creates resistance and reduces the speed of the object. Objects moving through water also experience buoyancy, which can counteract some of the drag force.
Why do currents curve in the northern hemisphere?
In the northern hemisphere, the Coriolis effect deflects moving objects to the right, causing currents to curve clockwise. This is due to the rotation of the Earth, which influences the direction of moving fluids like water.
Which arrow shows the direction that water was moving to make these ripple marks?
The arrow pointing away from the ripple marks indicates the direction in which water was moving to create them. This is because ripple marks form perpendicular to the direction of water flow.
How do you explain that the pencil appears broken in the glass of water?
A ray of light changes direction when it gets out of the water, and into the air. This is called "refraction".A ray of light changes direction when it gets out of the water, and into the air.

What is water continually moving in 1 direction called?
Water continually moving in one direction is typically referred to as a current. This movement can be caused by a variety of factors such as wind, tides, or differences in water temperature and density.
Does water resistance speed up moving objects?
Water resistance acts as a drag force on moving objects, slowing them down rather than speeding them up. The resistance depends on factors such as the shape and speed of the object moving through water.
How can refraction make objects look?
Refraction occurs when light changes speed as it moves from one medium to another, causing it to change direction. This change in direction can make objects appear distorted or bent when viewed through the refracting medium, such as a lens or water.
