Forces Vocabulary

2. Body Diagram - simplified representations in a problem of an object (the body), and the force vectors acting on it.
4. - the push or pull on an object with mass causes it to change its velocity.
6. - the force that resists motion when the surface of one object comes in contact with the surface of another.
9. Force - defined as is the sum of all the forces acting on an object.
10. - the condition of a system when neither its state of motion nor its internal energy state tends to change with time.
11. - the rate of change of velocity.
13. of Mass - a point representing the mean position of the matter in a body or system.
14. - the quantity of matter within a given object.

1. - the gravitational force with which the Earth attracts the masses towards its center.
3. - a quantity that has both magnitude and direction.
5. - the total amount of force acting on the object or body along with the direction of the body.
7. - 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
8. Field - a map of a force over a particular area of space.
9. - the international unit of measure for force.
12. Force - the force that surfaces exert to prevent solid objects from passing through each other
