1
Motion Vocabulary
2
The act or process of changing position or place. 1
3
A place or location 2
4
A system that uses coordinates to establish the precise position of objects in space and time. A group of objects that are not moving relative to each other. 3
5
The continuous change of position of a body with respect to a second body or to a reference point that is fixed. 4
6
The length of the path an object travels. 5
7
The distance and direction of an object’s final position from its initial position. 6
8
A quantity that is specified by both a size and a direction. 7
9
The distance an object travels per unit of time. 8
10
The speed of an object at a single instant of time. 9
11
The total distance an object travels divided by the total travel time. 10 V = 12 m 6 s = 2 m/s V = d ΔtΔt
12
The speed of an object and its direction of motion. 11 V = ΔdΔd ΔtΔt 3 m 6 s = 0.5 m/s
13
The gradient or steepness of a line on a graph. It is the ratio of the change in y over the change in x. 12 m = rise run m = y 2 - y 1 x 2 - x 1 m = 40 - 0 100 - 0 m = 40 100 m = 2.5
14
The equation for a straight line written in “slope-intercept” form. 13
15
The change in velocity divided by the time for the change to occur. 14
16
The acceleration that occurs in circular motion. 15
