force-levers Flashcards
Force=
Mass x acceleration
___ newtons of force are required for 1mm of p-a shear
260
newton’s first law of motion aka
law of inertia
law of inertia/first law
an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
newton’s second law of motion aka
law of force and acceleration
newton’s second law of motion/force and acceleration states
the acceleration of an object depends directly upon the object and inversely upon the mass of object
newton third law of motion aka, and what it states
- law of action and reaction
- for every action there is an equal and opposite reaction
____ is the force that resists the sliding of to objects in contact
friction
___ stress is the intensity of force perpendicular to the surface on which it acts, while ___ stress is the intensity of force parallel to the surface on which it acts
normal
shear
____ friction exists when two contacting surfaces are not currently sliding relative to e/o but do possess the potential for movement
static
____ friction is in cases when two surfaces are already sliding relative to each other, aka dynamic
kinetic
____ is the magnitude of applied force acting over a given area, is measured in pascals
pressure
____ is performed when a object is displaced by the application of a force, measured in Jules
-can be Pos or neg
work
- the energy an object possesses due to motion is called
- will have none if the object is not moving
kinetic energy
type of motion of one object with respect to a reference object
relative motion
