  2. ICFES examination - Wikipedia

    en.wikipedia.org/wiki/ICFES_Examination

    The internal structure of the exam is designed following evidence-centered design and states that skills (competencies) are defined by a series of affirmations. These affirmations are formulated using research-based evidence. Evidence is evaluated by tasks and items, which are composed of a context, a question, and four possible answers.

  3. Concept inventory - Wikipedia

    en.wikipedia.org/wiki/Concept_inventory

    The aims of the research include ascertaining (a) the range of what individuals think a particular question is asking and (b) the most common responses to the questions. Concept inventories are evaluated to ensure test reliability and validity. In its final form, each question includes one correct answer and several distractors.

  4. Kinematics - Wikipedia

    en.wikipedia.org/wiki/Kinematics

    In engineering, for instance, kinematic analysis may be used to find the range of movement for a given mechanism and, working in reverse, using kinematic synthesis to design a mechanism for a desired range of motion. [8] In addition, kinematics applies algebraic geometry to the study of the mechanical advantage of a mechanical system or mechanism.

  5. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    There are two main descriptions of motion: dynamics and kinematics.Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations.

  6. Quick return mechanism - Wikipedia

    en.wikipedia.org/wiki/Quick_return_mechanism

    In addition to the kinematic analysis of a quick return mechanism, there is a dynamic analysis present. At certain lengths and attachments, the arm of the mechanism can be evaluated and then adjusted to certain preferences. For example, the differences in the forces acting upon the system at an instant can be represented by D'Alembert's ...

  7. Kinetics (physics) - Wikipedia

    en.wikipedia.org/wiki/Kinetics_(physics)

    In physics and engineering, kinetics is the branch of classical mechanics that is concerned with the relationship between the motion and its causes, specifically, forces and torques.

  8. GRE Physics Test - Wikipedia

    en.wikipedia.org/wiki/GRE_Physics_Test

    The scope of the test is largely that of the first three years of a standard United States undergraduate physics curriculum, since many students who plan to continue to graduate school apply during the first half of the fourth year. It consists of 70 five-option multiple-choice questions covering subject areas including the first three years of ...

  9. Inverse dynamics - Wikipedia

    en.wikipedia.org/wiki/Inverse_dynamics

    Kinematics; Inverse kinematics: a problem similar to Inverse dynamics but with different goals and starting assumptions.While inverse dynamics asks for torques that produce a certain time-trajectory of positions and velocities, inverse kinematics only asks for a static set of joint angles such that a certain point (or a set of points) of the character (or robot) is positioned at a certain ...
