11
contact force
a force that acts only when one object touches another
New cards
12
field force
a force that acts between objects that are not touching; also called force at a distance

13
balanced forces
simultaneous forces whose pushes and pulls cancel each other out
New cards
14
net force
the vector sum of all the forces acting on an object
New cards
15
unbalanced forces
a collection of forced on an object that dont cancel out and thus cause an acceleration

free-body diagram
a sketch that shows an object and the forces acting on it; also called a force diagram
New cards
17
inertia
the tendency of matter to resist changes in its motion
New cards
18
law of inertia
the law that states that objects at rest and objects in motion continue in a straight line at a constant velocity unless acted on by a net external force; also called Newtons first law of motion
New cards
19
law of acceleration
the law that states that the acceleration of an object is directly proportional to the net force acting on the object and is inversely proportional to its mass; also called Newtons second law of motion
New cards
20
law of action-reaction
the law that states that for every action force, there is equal and opposite reaction force; also called Newtons third law of motion
New cards
21
tension
a pulling force that is transmitted through a rope, chain, or similar object '
New cards
22
natural force
the force that acts in a direction that is perpendicular to the surface where two objects make contact
New cards
23
gravity
a field force that acts between the masses of any two objects
New cards
24
law of universal gravitation
the law that states that the strength of gravity varies in direct proportion to the masses of the objects involved and inversely to the square of the distant between their centers of mass
New cards
25
