forces voca

4. rate at which velocity changes with time, in terms of both speed and direction.
6. force, the support force exerted by a surface against and object resting
7. an action (usually a push or a pull) that can cause an object to change its velocity or its shape
8. the force exerted on a body by gravity
11. body diagram a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition
12. force the total force acting on an object, calculated as the vector sum of all individual forces
13. the vector sum of two or more vectors
14. the amount of matter in an object

1. the force that resists motion when the surface of one object comes in contact with the surface of another.
2. of mass a hypothetical point where the entire mass of an object may be assumed to be concentrated to visualize its motion
3. If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object
5. a quantity that has both magnitude and direction.
7. field The push or pull on an object with mass causes it to change its velocity.
9. the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its velocity to change
10. the SI unit of force.
15. the rate of change in an object's position measured in units of distance per unit of time
