Rate of change - (new value - old value) / (time taken for change), Displacement - The distance and direction away from some specified origin, Speed (Instantaneous) - The rate of change of distance, Average speed - Total distance / time taken, Velocity - The rate of change of displacement, Acceleration - The rate of change of velocity, Force - A push or a pull, 1 newton - The force that accelerates a mass of 1 kilogram at 1 metre per second per second, Mass - A measure of the amount of stuff/substance/matter in a body, Weight - A force defined as "the force due to gravity on an object", Gravitational field strength - The force per unit mass experienced by a small test object placed at a point, Tension - The force within a stretched object (spring etc.) that pulls on the objects attached to its ends, Friction - A force that opposes the relative motion (or tendency towards motion) of two surfaces in contact, Fluid - Anything that flows, i.e. liquid or gas, not just liquid, Drag - The resistance to motion experienced by an object moving through a fluid, Normal contact force - The component of the interaction between two bodies in contact that is perpendicular to their interface, Upthrust - The upwards force exerted on an object that is wholly or partially immersed in a fluid, Terminal velocity - The maximum speed reached by an object falling through a fluid when the drag is equal to the weight of the object,
