Acceleration: The rate of change of the velocity of an object with respect to time.
Air resistance: A type of friction (i.e., a force that opposes
motion) which occurs between air and an object.
Affordance: Intrinsic qualities which can help determine usability. For example, ropes are good for binding and pulling but are not well suited to pushing.
Biochemistry: The application of chemistry to the study of
biological processes at the cellular and molecular level.
Data: Information collected for reference or analysis.
Dichotomous key: A classification tool consisting of a series of questions or statements with two choices in each step.
Fair test: An experiment to answer a scientific question where
one variable is changed, one variable is measured, and all others
variables remain the same.
Force: A push, pull or twist upon an object resulting from
interaction with another object. Forces only exist as a result of an
interaction, although interactions can involve non-contact forces such as
gravity.
Friction: A contact force resisting the motion of one object or medium against another.
Graph: A visual representation of data usually depicted on X and Y axes.
Gravity: A non-contact force of attraction between objects, particularly evident with celestial bodies.
Heliocentric model: An astronomical model in which the Earth and planets revolve around the Sun.
Machine: A device that transmits or modifies force and motion.
Research: “The creation of new knowledge and/or the use of
existing knowledge to generate concepts, methodologies, inventions, and
understandings that address timely and important gaps and issues” (Centre
for Education Statistics and Evaluation [CESE] & MH Consulting Group
[MHC], 2024, p. 21).
Symmetry: Shapes and objects are symmetrical if they can be
divided into two equal parts along a straight line.
Table: A grid of labelled rows and columns designed to record data.
Torque: A measure of the force that can cause an object to rotate about an axis.
Torque multiplier: A tool used to provide a mechanical advantage in applying torque. For example, using low gears on a bicycle to ride up a hill makes it easier to pedal.
Velocity: The directional speed of an object.
Venn diagram: A visual classification tool using overlapping circles or other shapes to illustrate relationships between two or more sets of items.
