Forces Vocab

3. a force that opposes the relative motion between surfaces in contact.
6. a simple, visual representation that shows all the forces acting on a single object.
9. the support force exerted by a surface on an object in contact with it, acting perpendicular to the surface
12. a single force, velocity, or vector that has the same combined effect as two or more other vectors acting together
15. a region of space where an object would experience a non-contact force.
16. the overall force acting on an object when all individual forces are combined, and it determines the object's acceleration

1. the unique point in an object or system where all its mass can be considered to be concentrated for the purpose of analyzing motion
2. a state of balance where the net force and net torque acting on an object are both zero
4. a quantity that has both a magnitude (size or amount) and a direction.
5. a push or pull on an object that can cause it to change its motion
7. the rate at which an object's velocity changes
8. an object's resistance to any change in its state of motion
10. a measure of the amount of matter in an object.
11. the force of gravity on an object
13. the rate at which an object covers distance over time, with no regard to direction
14. the SI unit of force.
