Physics Vocabulary

2. Three principles that explain the relationship between an object's motion and the forces applied to it;at least two laws always apply
4. forces acting on an object that cancel each other out causing a net force of zero and causing no change in movement.
7. Speed in a given direction
11. Any push or pull between two objects,measured in Newtons (N)
13. Stored energy of an object due to position, condition, or composition.
14. Newton's second law of motion states that the acceleration of an object depends on its mass and the amount of force applied where F=ma, objects accelerate in the direction of the unbalanced force.
17. The sum of all forces action on an object within a system, includes both magnitude (strength) and direction.
18. A force acting directly in contact with an object
19. change in an object's position or location.
21. Net force greater than zeros that cause changes in motion of an object in the direction of the greater force
23. Group of items interacting to form a unified whole
24. energy of objects in motion

1. Newton's third law states that all forces occur in contact pairs where every action force has a reaction force that is equal in strength and opposite in direction.
3. The rate of change at which an object moves a distance over time.
5. Gravity is the pull toward another object based on its mass. Gravity is always moving objects down at 9.8m/s2
6. A force that is opposite of motion between two surfaces that are touching causing it to slow down.
8. The tendency of all objects to resist change in motion dependent on mass, to keep doing what they are already doing.
9. Support force of a surface an object is in contact with preventing it from falling.
10. unit of measurement of force (N)
12. The rate at which velocity changes (speed or direction) over time as a result of unbalanced forces and mass of the object.
15. Newton's First Law states that an object's motion will not change unless an unbalanced force acts on it.
16. The amount of matter in an object measured in grams or kilograms
20. Speed that is steady or unchanging
22. Total distance traveled divided by the total amount of time taken.
