Science Vocab Part 2

the rate that velocity changes per unit time and the direction it changes in

the examination of the performance of an instrument in an experiment whose outcomes are known, for the purpose of accounting for the inaccuracies inherent in the instrument in future experiments whose outcomes are not known

the net force that acts to result in the centripetal acceleration. It is not an individual force, but the sum of the forces in the radial direction. It is directed toward the center of the circular motion.

a process that involves the formation or breaking of chemical bonds

the mass of a substance for a given unit volume

the change in position of an object. Computed from the final position minus the initial position.

a state at which the forward and reverse reaction proceed at the same rate.

that which acts on an object to change its motion; a push or pull exerted on one object by another.

the number of cycles or repetitions per second

a mixture that is not uniform in composition

a mixture in which the components are uniformly distributed

the tendency of an object to follow Newton’s First Law, the law of inertia. That is the tendency of an object to remain at rest or in motion with constant velocity unless acted on by a force.

atoms of the same element, with different numbers of neutrons, and hence a different atomic mass

the coordinate used to measure positions on the Earth north or south of the Earth’s equator

the coordinate used to measure positions on the Earth east or west of the prime meridian, which goes through Greenwich, England

a process of cellular reproduction where the daughter cells have half the amount of chromosomes.

the loss of electrons by a substance in a chemical reaction

an observation that includes characteristics other than amounts or measurements; may include shapes, colors, actions, and odors.

an observation that includes characteristics of measurements or amounts

the amount of solute that can be dissolved completely in a solvent at a given temperature

solid, liquid, and gas. In solids, atoms or molecules are held in place. The shape and volume of a solid usually do not vary much. In liquids atoms or molecules can move, but their motion is constrained by other molecules. Liquids assume the shape of their container. In gasses the motion of atoms or molecules is unrestricted. Gases assume both the volume and the shape of their containers and they are easily compressible.

the study of the surface features of the planet primarily through mapping

the rate that a position changes per unit time and the direction it changes in.

another name for potential difference
