PHYSICS MID 2 Flashcards
refers to push or pull upon a object as a result of its interaction
FORCES
two kinds of forces
CONTACT
NON CONTACT
force that surface exerts to prevent solid object from passing through each other
NORMAL FORCE
force generated by two surfaces that contact and slide against each other
FRICTION
after overcoming friction
ABRASION
force along the length of a medium especialy force carried by rope or cable
TENSION FORCE
force on a object can be felt as pushing or puling effect on it
APPLIED FORCE
force of gravity ,that pulls object with mass toward each other
GRAVITATIONAL FORCE
the repulsive or attarction interaction between any two charged bodies
ELECTRICAL FORCES
between two moving charges effect exerted upon either charge by force field
MAGNETIC FORCE
used to show the relative magnitude and direction of all forcres acting upon an object in a given situation
FREE BODY DIAGRAMS
free body diagrams is an example of?
VECTOR DIAGRAMS
summation of all forces acting on a system
NETFORCE
weight
w
friciton
f
tension
T
alt to weight/ for inclined
FGRAV
normal force
FN
force applied
FAPP
action of changing location or position
MOTION
the study of motion without regard to the forces or energies that may be involved is called
KINEMATICS
set of coordinates that can be used to determine positions and velocities of objects in that frame
FRAME OF REFERENCE
moves relative to one another
FRAME OF REFERENCE
frame of reference where newtons analysis works are called?
INERTIAL FRAMES
true for inertial frame sof reference
PRINCIPLE OF INERTIA
property of matter in which an object at rest remain at rest; object at motion remain at motion
INERTIA
when a body does not seem to be acting in accordance with inertia
NON INERTIAL FRAME OF REFERFENCE/ accelerating
motion of objects in an inertial reference system
NEWTON’S LAWS
3 laws of motion according ti newton
LAW OF INERTIA
LAW OF ACCELERATION
LAW OF ACTION AND REACTION
if the resultance force is zero
BALANCED FORCE
if the force is not equal to zero
UNBALANCED FORCE
the greater the mass
THE GREATER THE INERTIA
proportional to the netforce action on it and is in the same direction of the net force
ACCELERATION OF AN OBJECT
acceleration is proportional to
FORCE
acceleration is inversely proportional to
MASS
for every action there is an equal but opposite reaction
LAW OF ACTION AND REACTION
a condition where there is no change in a state of motion of a body
EQUILIBRIUM
if object in equilibrium is at rest
STATIC EQUILIBRIUM
if object is moving with constant velocity
DYNAMIC EQUILIBRIUM
netforce acting on equilibrium is
ZERO
type of contact force that resist and oppose movement
FRICTION FORCE
one present between two objects that are not moving in respect to each other
STATIC FRICTION
friction is the resistance betwen moving layers of liquid
VISCOSITY
force that acts upon between two moving solid object surfaces
KINETIC FRICTION
change in position when a force acts upon an object to cause a displacemetn of the object
WORK
unit of work
JOULES
if same direction
ZERO DEGREES
if magkasalungat
180 DEGREES
if one horizontal one is vertical
90 DEGREES
defined as the rate of energy transfer
POWER
rate of doing work
POWER
formula for work
w = f times d times cos theta
unit of power
WATT
formula power
WORK/ TIME
triangle power work
PWT
triangle weight
MWG
