Force & Motion Vocab
6th grade Science Force and Motion Vocabulary
Term | Definition |
---|---|
reference point | a point used to find or describe the location of an object or the starting point used to describe the motion or position of an object |
position | the location of an object or an object's distance and directions from a reference point |
direction | the path that an object is moving or facing |
motion | a change in position or the process of changing position |
balanced force | equal forces on an object that do not change the position or motion of an object; balanced forces = no movement |
unbalanced force | a force on an object that causes change in the position or motion of an object; one side has more force than another side of an object |
resting position | when an object remains in the same location or spot |
speed | the rate of change of position (or distance traveled) with respect to time |
velocity | the speed and direction of an object |
displacement | the difference between the initial or starting position and the final position of an object that has been moved |
x-axis | the horizontal line with labels on a coordinate grid; the independent variable (often time) is represented on the x-axis |
y-axis | the vertical line with labels on a coordinate grid; the dependent variable (often distance) is represented on the y-axis |
distance-time graph | illustrates change in motion; time is graphed on the x-axis and distance is on the y-axis |
speed-time graph | illustrates the speed of an object on the y-axis and the time on the x-axis |
force | a push or pull (examples are gravity, friction, magnetism, wind, etc.) |
