Glossary

A change in velocity over a period of time.

Free-falling object is an object that is falling under the sole influence of gravity; measured at 9.8 m/s/s.

Amount of electrical energy flowing through an appliance at any given time.

The magnitude of change in the oscillating variable with each oscillation within an oscillating system.

Operating or acting in conjunction with another. In physics this would indicate that two vectors are coming out of the same point at the same time.

The point on a wave with the maximum value or upward displacement within a cycle.

The shortest distance from the initial to the final position of a point

A numerical description of how far apart objects are. In physics, distance may refer to a physical length.

refers to forces which act on a solid object in the direction of motion.

Any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape.

The force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

Are two equalities that deal with the conservation of charge and energy in electrical circuits.

Waves that have the same direction of vibration as their direction of travel, which means that the movement of the medium is in the same direction as or the opposite direction to the motion of the wave.

A quantity with no direction; just a numeric value.

States that the current through a conductor between two points is directly proportional to the potential difference across the two points.

A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit.

Inversely related or proportional; opposite.

The opposition to the passage of an electric current through that element

A passive two-terminal electrical component that implements electrical resistance as a circuit element.

Single vector that is the vector sum of two or more other vectors.

A series circuit is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths.

Change in distance over time; direction is not associated with this value.

A moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer.

Lowest point of the wave.

A quantity with both direction and magnitude.

A change in distance or displacement over any given period of time.

 Known as electrical potential difference or electric tension is the potential difference between two points.

A disturbance (an oscillation) that travels through space in time, accompanied by the transfer of energy.

The distance over which the wave's shape repeats.
