- In physics, a force does work when it acts on a body and there is a displacement of the point of application in the direction of the force. Energy is the capacity to do work; the influence required to perform an action. The amount of energy in a system is the amount of change that can be made to it.$5.24$7.50Save $2.26
Ranking Task: Work Done by a Figure on the Stairs of M.C. Escher's Relativity
The worksheet uses the 1953 lithograph to prompt students to calculate work in a variety of scenarios on the staircases. The worksheet teaches Ss the formula for physical work as force times distance and can be used for an in-classroom or homework assignment.
Maurits Cornelis Escher, or M. C. Escher, was a Dutch graphic artist who lived from 1898 to 1972. A fine example of M.C. Escher's focus on unusual, and often conflicting, points of view, this is perhaps Escher's best-known print on the theme of relativity.
Ranking Task Exercises are a type of conceptual exercise that asks Ss to make comparative judgements about a set of variations on a particular physical situation. The basic structure of a Ranking Task has four elements:
- the description of the situation, including the constraints and the basis for ranking arrangements
- a set of figures showing the different arrangements to be compared
- a place to write down the ranking of the variations
- a place to write down the reasoning behind the chosen ranking
