Unit 3: Balanced forces vocab

5. An inward pulling force created when a solid object is stretched.
8. Any change in an object's velocity, including speed or direction.
9. A force without an equal and opposite force acting on the same object
10. An upward force exerted on an object by a solid surface.
15. A visual representation showing all forces acting on an object as arrows.
16. A force that acts between objects without physical contact.
18. Any force that can only occur when two objects are touching.
19. A contact force opposing an object's motion through water.
21. An attractive non-contact force between any two masses.
22. The tendency of an object to resist changes in its velocity.
23. The force exerted on an object's mass by gravity.
25. The rate at which an object covers distance over time.
26. Forces that are equal and opposite, resulting in zero net acceleration.

1. A force exerted on an object by a person, animal, or machine.
2. A push or pull.
3. The equal and opposite force paired by Newton's third law.
4. For every action force, there is an equal and opposite reaction force.
6. Net force equals mass times acceleration (F = ma).
7. The overall combined force acting on an object.
11. A reaction force produced by expelling liquid or gas.
12. The standard SI unit used to measure force.
13. A contact force that acts on an object when it hits another object
14. The amount of matter in an object, measured in kilograms. *Mass does NOT depend on gravity
15. A contact force that resists motion between surfaces.
17. The speed of an object in a certain direction Velocity is different from speed because it must have a specific direction. A stationary object has zero velocity.
20. A force that resists an object's motion through air.
24. An object maintains constant velocity unless acted upon by a net force.
