Force and motion #1

4. measures weight; gravitational force
8. the collection of all points whose coordinates satisfy a given relation (such as a function)
9. unequal forces on an object that may result in a change in position, direction, or motion
11. any of various elementary mechanisms formerly considered as the elements of which all machines are composed and including the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw
12. speed the total distance traveled by an object over a total amount of time
13. a graph in which points representing values of a variable for suitable values of an independent variable are connected by a broken line
14. a measure of how fast something moves; rate of motion
15. energy of motion

1. equal and opposite forces on an object that result in no change in position, direction, or motion
2. when an object’s speed remains unchanged
3. how far an object has moved from its original position; the difference between the final and initial positions
5. stored energy of an object because of its position or shape
6. the line or course on which something is moving or is aimed to move or along which something is pointing or facing
7. change in an object’s motion (position, direction, speed); caused by unbalanced forces
10. a push or pull exerted on an object in order to change the motion of the object; force has size and direction.
16. the unit of force
