science

2. speed in a given direction; distance divided by time along with a stated direction
3. forces that produce a nonzero net force, causing an object to move, stop moving, or change direction
8. the acceleration of an object depends on the object's mass and on the net force acting on the object; aka 'Law of Acceleration'
9. the combination of all forces acting on an object; determines whether or not the object will move and also the direction of movement
10. a place or object used for comparison to determine if an object is in motion
11. the state in which one object's distance from another object is changing
12. the rate at which velocity changes; increasing speed, decreasing speed, or changing direction; (final speed minus initial speed) divided by time = acceleration
13. the distance an object travels per unit of time; speed= distance divided by time
14. the overall rate of speed at which an object moves at a non-constant rate; total distance divided by total time = average speed

1. an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force; aka 'Law of Inertia'
4. how much ground is covered by a moving object from start to finish
5. equal forces acting on an object in opposite directions; results in 0 net force and no change in motion
6. the tendency of an object to resist any change in motion; is dependent upon the object's mass
7. if an object exerts a force on another object, the second object exerts a force of equal strength in the opposite direction on the first object; aka 'Action/Reaction Law'
15. the steepness of a line on a graph, equal to its vertical change divided by its horizontal change; slope = rise divided by run
