1. a vector quantity that is a measure of the push or a pull that acts on an object because of an interaction between the object and its environment
force
2. the vector combination or sum of all forces that act on an objec
net force
3. two values changing in the same directions. as one value doubles, the other also double, or if one is halved, the other is also halved
directly proportionalĀ
4. two values changing in the opposite directions, as one doubles the other is halvedĀ
inversely proportionalĀ
5. also known as the law of inertia- every object continues in it state of rest, or motion in a straight line at a constant speed, unless acted upon by a non-zero net force
newton's first law
6. the acceleration produced by a non-zero net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the object
newton's second law
7. the force that acts between materials that touch and that opposes motion or impending motion. it depends on the nature of the surfaces and amount of force
friction
8. between objects that are not yet moving
static friction
9. between objects that are moving
kinetic friction
10. the ratio of the frictional force acting on the object to the normal force acting on the object
coefficient of friction
11. a simple diagram in which the body is represented by a dot and that shows all the forces acting on a body as pointing outward from the dot
free-body diagram
