6. newtons third law
8. the sum of all forces acting on an object within a system
10. net force greater than zeros that cause a change in motion in the direction of the greater force
12. three principles that explain gravity
15. newtons second law
17. newtons first law
18. support force of a surface an object is in contact with preventing it from falling
19. speed that is steady or unchanging
21. stored energy of an object
23. group of items interacting to form a unified whole

1. energy of objects in motion
2. a force that is opposite of motion between two surfaces that are touching causing it to slow down
3. change in an objects position or location
4. any push or pull between two objects, measured in newtons
5. gravity is the pull toward another object based on its mass.
6. total distance traveled divided by total amount of time taken
7. a force acting directly in contact with an object
9. forces acting on an object that cancel each other out causing a net force of zero and no change in movement
11. is the amount of matter in an object measured in grams or kilograms
13. the rate at which velocity changes over time as a result of unbalanced forces and the mass of the object
14. unit of measurement of force
16. the rate at which an object moves a distance over time
20. speed in a given direction
22. the tendency of all objects to resist change in motion dependent on mass, to keep doing what they are already doing
