# What is energy flow diagram?

Energy Flow Diagrams (often also referred to as Energy Flow Charts) are used to show energy and energy transformation visually and quantitatively. This may include primary energy used as raw fuels to feed into a system, energy supply, conversion or transformation, losses and energy being used.

## What is an LOL diagram in physics?

LOL diagrams are a way to represent how the energy is stored in the chosen system during various snapshots and to represent any changes in total energy for the system. Each “L” represents how the energy is stored during a particular snapshot (instant). The “O” shows the objects inside and outside the system.

## What is an energy diagram physics?

An energy diagram shows how the potential energy of an object depends on position and tells you all kinds of things about the motion of the object.\nHere’s an example energy diagram for the boulder:\n\nThe potential energy curve shows how much potential energy the boulder has at each position.

## What is a momentum bar chart?

Momentum conservation bar chart A properly drawn bar chart will show the same total momentum on the “before” side and the “after” side. Each side of the chart shows a bar for each object in the system. The size of the bar is determined by calculating the momentum p of the object in the initial or final state.

## What is Ke formula?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## What is energy bar chart?

A work-energy bar chart represents the amount of energy possessed by an object by means of a vertical bar. The length of the bar is representative of the amount of energy present, with a longer bar representing a greater amount of energy. In a work-energy bar chart, a bar is constructed for each form of energy.

## What are some advantages to representing the energy with pie charts?

Advantages of a Pie Chart It represents data visually as a fractional part of a whole, which can be an effective communication tool for the even uninformed audience. It enables the audience to see a data comparison at a glance to make an immediate analysis or to understand information quickly.

## What is e ch in chemistry?

Epichlorohydrin (1-chloro-2,3-epoxypropane; ECH) is a clear, colorless liquid with a sweet, pungent odor mostly used to make epoxy resins, also used in water treatment, paper chemicals, synthetic rubbers, and surfactants.

## What is an energy in physics?

energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

## What are energy flow models?

The energy flow models link the trophic levels with each other showing the inputs and losses of energy at each trophic level. The flow of energy in an ecosystem takes place through the food chain and it is this energy flow which keeps the system going.

## What is an example of energy flow?

An example of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use. Carnivores subsequently feed on the herbivores and, finally, other carnivores prey on the carnivores.

## Why is it called a Sankey diagram?

History. Sankey diagrams are named after Irish Captain Matthew Henry Phineas Riall Sankey, who used this type of diagram in 1898 in a classic figure (see diagram) showing the energy efficiency of a steam engine.

## How does a range chart work?

Three rules of range bars: Each range bar must have a high/low range that equals the specified range. Each range bar must open outside the high/low range of the previous bar. Each range bar must close at either its high or its low.

## What is the conservation of momentum equation?

The equation describing the Law of Conservation of Momentum is p=p′ , where p is the system’s initial momentum and p′ is the system’s final momentum. This equation can be expanded using the definition of momentum into m1v1+m2v2=m1v′1+m2v′2 m 1 v 1 + m 2 v 2 = m 1 v 1 ′ + m 2 v 2 ′ .

## What are 4 types of kinetic energy?

There are five main types of kinetic energy: radiant, thermal, sound, electrical, and mechanical. Radiant energy concerns ultraviolet light and gamma rays that are continually moving around in the universe. Sound energy is kinetic energy in the form of vibrations and noise, such as someone banging drums.

## What is the Joule formula?

Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2]. Therefore, Joule is dimensionally represented as [M1 L2 T-2].

## What is the potential energy of a spring?

Potential Energy of a Spring Formula String potential energy = force × distance of displacement. Also, the force is equal to the spring constant × displacement.

## In what way is mass related to potential energy?

The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.

## At what point does the skater have the most kinetic energy?

Thus, the skater’s kinetic energy is greatest at the lowest point of the track, where the skater is moving the fastest.

## When should you not use a pie chart?

If you still feel the urge to use them, make sure you only use them for a percentage breakdown where each slice represents a certain percentage out of 100% and order the slices in size to make it easier to read. Never use a pie chart if it has more than 5 slices and never-ever make it 3D.
