Friction is the force that opposes the motion of one surface as it moves across another surface. In an area where the river is deep, less water touches the streambed. In an area where the river is shallow, more water touches the streambed. The streambed's shape and roughness will also affect the amount of friction.

Similarly, you may ask, how do you calculate the force of water moving?

Use the formula F=ALC/T to calculate the force of the moving water. F=force, A=average area, L= stream length (20 feet), C=coefficient for the bottom of the water bed, and T=time traveled.

Also, what force of moving water can move rocks? If the pores in rocks and sediments are connected, gravity allows the water to move slowly through them. However, the smaller the opening, the harder it is for gravity to cause water movement. The second force, molecular attraction, slows the flow of water through small pores.

Then, what is the force of water?

It can be frustrating because the water tries to push you back up to the surface as you're swimming downward. The name of this upward force exerted on objects submerged in fluids is the buoyant force. It has to do with differences in pressure between the bottom of the submerged object and the top.

How do you calculate water in a river?

Figure Three: Finding the flow rate using a float and a meter stick. The float method (also known as the cross-sectional method) is used to measure the flow rate for larger streams and rivers. It is found by multiplying a cross sectional area of the stream by the velocity of the water.

### How do you find the buoyant force of an object?

The buoyant force on a submerged object is equal to the weight of the fluid displaced. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by measuring its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).

### How do you calculate dynamic pressure?

The General Pressure Equation
As noted, pressure is force divided by area, and force is mass times acceleration. Mass (m), however, can also be written as the product of density (ρ) and volume (V), since density is just mass divided by volume. That is, since ρ = m/V, m = ρV.

### Is water a force?

Running water, that is water that flows on the Earth's surface in streams and rivers, is the most powerful natural agent operating on the surface, and changes the face of the Earth. Gully erosion is more spectacular, because deep trenches may develop where water is concentrated into streams.

### What is meant by buoyant force?

Definition of buoyant force. : the upward force exerted by any fluid upon a body placed in it — compare archimedes' principle.

### What causes buoyant force?

The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed. The buoyancy force always points upwards because the pressure of a fluid increases with depth.

### What is an example of a buoyant force?

The buoyant force is simply less than the gravitational force. An obvious example of this would be throwing a pebble into a pond. It would sink because it is negatively buoyant, but it still has a buoyant force acting upon it, nonetheless.

### What do you mean by force?

In science, force is the push or pull on an object with mass that causes it to change velocity (to accelerate). Force represents as a vector, which means it has both magnitude and direction.

Archimedes's

### How does buoyant force work?

Buoyancy is the upward force we need from the water to stay afloat, and it's measured by weight. The trapped air weighs much less than the weight of the water it displaces, so the water pushes up harder than the life jacket pushes down, allowing the life jacket to remain buoyant and float.

### What are the effects of water resistance?

Water resistance is also the force responsible for making it difficult for us to move through the water. If we turn sideways it becomes easier as we become streamlined. Use examples of fish body shapes – how are they appropriate for moving smoothly and easily through water.

### What is a dam wall?

A dam is a barrier that stops or restricts the flow of water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.

### What is the rate of erosion?

The erosion rate measures the amount of soil mass lost over a specified time period. If 30,000 kilograms of soil was lost over four years, then: Erosion rate equals 30,000 divided by 4, or 7,500 kilograms per year.

### What is the difference between weathering and erosion?

Erosion is the removal and transport of surface materials (soil, rocks, mud, etc.) through the actions of wind, water, and ice. The primary difference between weathering and erosion is that weathering occurs in place whereas erosion involves movement to a new location.

### What type of weathering happens when sand wears away rock?

Chemical weathering occurs when rocks are broken down by a chemical change. Rainwater can become slightly acidic by absorbing carbon dioxide in the atmosphere and this reacts with the mineral grains in the rock giving rise to new minerals and salts.

### What is Isweathering?

Weathering is breaking down rocks, soil, and minerals as well as wood and artificial materials by contacting the atmosphere, water, and biological organisms of the Earth. Weathering takes place in situ, i.e. in the same place, with little or no movement.

### What are the causes or agents of weathering?

Agents responsible for weathering include ice, salts, water, wind and plants and animals. Road salt and acids represent a form of chemical weathering, as these substances contribute to the wearing away of rocks and minerals as well.

### Where is the oldest layer of rock located?

Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.
