FORCE/MOTION
6.8BCD CHANGES IN FORCE & MOTION
Question | Answer |
---|---|
RESTING POSITION | Refers to an object remaining in the same spot relative to another object. |
MOTION | Change in an object's position with respect to time and in comparison with the position of other objects used as reference points. |
DIRECTION | Straight path that an object can move along. |
SPEED | Rate of change of position (or distance traveled) with respect to time; units measured are expressed as distance per time (ex: meters per second). |
LINE GRAPH | Graph in which the data are represented by points connected by one or more lines. |
DISTANCE-TIME GRAPH | Type of graph that illustrates changes in motion; time is graphed on the x-axis and distance is graphed on the y-axis. |
X-AXIS | Horizontal line with labels on a coordinate grid; time is represented in the x-axis. |
Y-AXIS | Vertical line with labels on a coordinate grid; distance is represented on the y-axis. |
AVERAGE SPEED | Calculated by dividing total distance an object travels by total time it took the object to travel the distance (s = d/t); speed describes the rate of movement. |
FORCE | Push or pull that can change the motion of an object, measured with a spring scale in Newton (N) units. |
BALANCED FORCES | Separate forces on an object that, when combined, do not change the movement of the object. |
UNBALANCED FORCES | Forces on an object 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. |
