2026
An accessible, low-cost apparatus for measuring human muscle force–velocity–power relationships was developed using inexpensive materials, a 3D-printed gear, a smartphone accelerometer, and Python freeware. Validation against a gold-standard ergometer demonstrated physiologically relevant measurements while providing equitable, hands-on learning opportunities in an undergraduate classroom setting.

Relationship between Average and Marginal Costs

Marginal Cost (MC) is a variable cost that refers to the additional expenses incurred by the firm when producing one more unit of a good or service. The Average Variable Cost (AVC) represents the total variable costs per unit produced and the Average Total Cost (ATC) represents the total cost per unit produced. As production increases, the relationship between MC and AVC, and between MC and ATC, are the same. The following description will refer to both of these cost terms simply as Average...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Humans have been attempting to properly classify living things since Aristotle made the first attempt during the 4th century BC. Aristotle’s system was improved upon during the Renaissance and then, subsequently, by Carolus Linnaeus in the mid 1700’s. These more formal classification and organization systems grouped species by their physical similarity to one another. For example, all vertebrates have a backbone, but invertebrates do not. Traits like the backbone are called synapomorphies,...

Forming an Evolutionary Hypothesis ExpandNOTE: A cladogram is an important tool for forming an evolutionary hypothesis. A cladogram is a tree-shaped chart used to depict the hypothetical genealogical relationships between species. The tips or leaves of the chart represent specific species and the branches of the tree are different lengths. The different lengths represent the degree of change between each of the species. The common ancestor of all of the species that a specific line branches...
FAQs
Fixed costs provide the constant component of a cost relationship, while variable costs change as activity changes. A total-cost model combines these parts so analysts can examine how production level affects overall expenses. Separating the components also helps identify whether a change in total cost comes from a stable expense or from increased or decreased activity.
Average cost describes cost in relation to the quantity produced, giving a measure for comparing output levels. Marginal cost focuses on how cost changes when production changes. Considering both measures prevents analysts from treating total expenses as the only useful result and supports more precise comparisons of production alternatives.
A cost relationship changes when its relevant input changes, such as production level, time, or quantity. Functions, tables, and graphs make these changes visible by linking the input to expense outcomes. Examining that link helps analysts interpret patterns, compare alternatives, and judge how sensitive financial results are to different activity levels.
Begin by identifying the activity measure and the expense information available. Classify expenses as fixed or variable, then organize the values in a table, graph, function, or equation. Combine the components to represent total cost, and calculate average or marginal measures when needed. The resulting model can then be used to compare output levels or alternatives.
Break-even analysis uses the connection between production activity and total expense to evaluate financial outcomes at different levels. By representing costs mathematically, analysts can identify the output conditions relevant to breaking even and compare those conditions with pricing or production alternatives. This gives decision-makers a structured basis for evaluating whether an activity level is financially viable.
A cost model links planned activity with expected expenses, making it useful for budgeting. It can also support resource allocation by allowing alternatives to be compared using their modeled cost outcomes. Because the relationships can be expressed with equations, tables, or graphs, analysts can organize assumptions clearly and examine how different production or quantity choices affect financial planning.
Each mathematical representation emphasizes a different aspect of the same cost information. Tables organize numerical values, graphs display patterns across activity levels, and functions or equations express the relationship in a form that supports calculation. Using these forms together strengthens data interpretation, improves comparison of alternatives, and connects mathematical analysis with applied economic decisions.
