forces

1. The amount of matter in an object; a measure of inertia. How much matter something contains.
3. The distance traveled per unit of time. How fast something is moving (no direction needed).
7. Force The total force acting on an object after combining all individual forces. The overall push or pull that determines an object’s acceleration (2 words).
8. A quantity with both magnitude and direction. Has size and direction—like velocity or force.
9. The gravitational force on an object’s mass. The pull of gravity on an object.
10. The force that resists motion between surfaces in contact. The resistance you feel when sliding an object.
12. When all forces on an object are balanced. The state where all pushes and pulls cancel out.
14. A single vector representing the combination of two or more forces. The combined effect of multiple vectors.
15. Force The support force exerted by a surface perpendicular to the object resting on it. The upward push from a surface that balances your weight (2 words).

2. The rate of change of velocity. How quickly an object’s speed or direction changes.
4. A push or a pull on an object. A push or pull that can cause motion.
5. of Mass The point in an object where its mass is evenly distributed. The “balance point” of an object (3 words).
6. Field A region of space where an object experiences a force (like gravity or magnetism). The invisible region around an object that can push or pull others (2 words).
10. Diagram A sketch showing all the forces acting on a single object. A drawing with arrows showing every force on one object (3 words).
11. The SI unit of force (and the scientist who defined motion laws). The unit for measuring force—or the man who studied gravity.
13. The tendency of an object to resist changes in motion. The stubbornness of matter—it resists change!
