What are energy graphs?

What are energy graphs?

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. The potential energy curve shows how much potential energy the boulder has at each position.

What is the graph that represents energy called?

Often, you can get a good deal of useful information about the dynamical behavior of a mechanical system just by interpreting a graph of its potential energy as a function of position, called a potential energy diagram.

What are energy bar charts?

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.

How do you find total energy from a graph?

For a given position, the gap between the total energy line and the potential energy line equals the kinetic energy of the object, since the sum of this gap and the height of the potential energy graph is the total energy.

What does an energy diagram illustrate?

The energy changes that occur during a chemical reaction can be shown in a diagram called a potential energy diagram, or sometimes called a reaction progress curve. A potential energy diagram shows the change in potential energy of a system as reactants are converted into products.

What is the energy equation?

The equation developed by Albert Einstein, which is usually given as E = mc2, showing that, when the energy of a body changes by an amount E (no matter what form the energy takes), the mass (m) of the body will change by an amount equal to E/c2.

What are two main types of energy?

Many forms of energy exist, but they all fall into two basic categories:

• Potential energy.
• Kinetic energy.
