Forces Vocabulary

3. a contact force that resists the relative motion between surfaces in contact
6. a simplified graphical representation of all the external forces acting on a single object
9. a contact force exerted by a surface on an object, acting perpendicular to the surface
12. the single vector that represents the combined effect of two or more vectors, such as forces or velocities
15. a force exerted by an object over a distance without direct contact, through the creation of a field
16. the total force acting on an object, calculated as the vector sum of all individual forces

1. the average location of an object or system's mass, and it behaves as if all the object's mass were concentrated at that single point
2. a state where the net force and net torque acting on an object are both zero, meaning there is no change in its motion
4. a quantity that has both magnitude (size) and direction
5. a push or pull on an object that results from its interaction with another object
7. the rate of change of velocity, meaning how quickly an object's velocity
8. the property of an object that resists changes to its state of motion
10. a measure of the amount of matter in an object, and it also quantifies an object's inertia, or resistance to a change in motion
11. force of gravity on an object
13. the rate at which an object moves, defined as the distance it travels divided by the time it takes
14. the overall force acting on an object, found by adding all the individual forces together
