### Changes in Force and Motion

TermDefinition
Resting Position Refers to an object remaining in the same spot relative to another object.
Motion The change in an object's position with respect to time and in comparison with the position of other objects used as reference points.
Direction the path that an object is moving or facing.
Speed The rate of change of position (or distance traveled) with respect to time; units in which speed is measured are expressed as distance per time (example: meters per second).
Distance-Time Graph This type of graph illustrates changes in motion. Time is graphed on the ex-axis and distance is graphed on the y-axis
Line Graph A graph in which the data are represented by points connected by one or more lines.
X-Axis The horizontal line with labels on a coordinate grid; time is represented on the x-axis.
Y-Axis The vertical line with labels on a coordinate grid; distance is represented on the y-axis.
Average Speed Average speed is calculated by dividing the total distance an object traveled by the total time it took the object to travel the distance (s=d/t). Speed describes the rate of movement.
Force a push or pull that can change the motion of an object, measured with a spring scale in Newton (N) units.
Balanced Forces Forces on an object that do not change the motion of the object.
Unbalanced Forces Forces on an object that cause that cause change in the motion of the object.
Potential Energy Energy that is stored in a system or object.
Kinetic Energy Energy of motion.
