PHYSICS QUIZ Flashcards
action of changing location or position
MOTION
set of motion without regard to forces or energies involved
KINEMATICS
set of coordinates that can be used to determine positions and velocities of objects in that frame
FRAME OF REFERENCE
frames of reference where newtons analysis works
INERTIAL FRAMES
the property of matter in which an object that is at rest remains at rest and an object moving remain moving in a straight line unless another force acts upon it
INERTIA
true for intertial frames of reference
PRINCIPLE OF INERTIA
when a body does not seem to be acting in accordance with inertia
NON INTERTIAL FRAME OF REFERENCE
refer to the motion of objects in an inertial reference frame
NEWTONS LAW
objects in motion will stay in motion and objects at rest will stay at rest unless acted upon by an unbalanced force , WHAT LAW
FIRST LAW OF MOTION / LAW OF INERTIA
vector sum of all the forces acting on a bodyb
NET FORCE
if fnet equals zero
BALANCE FORCE
if the fnet is not equal to zero
UNBALANCE FORCE
the greater the mass
THE GREATER THE INERTIA
accelaration of an object with constant mass is proportional to the net force action on it and is in the same direction of the net force
SECOND LAW OF MOTION/
LAW OF ACCELERATION
acceleration is proportional to?
FORCE
acceleration is inversely proportional to ?
MASS
formula for weight
W = MG
formula for force
F=MA
for every action, there is an equal and opposite reaction
THIRD LAW OF MOTION/ LAW OF ACTION AND REACTION
condition when there is no change in state of motion of a body
EQUILIBRIUM
if an object is at rest in equilibrium
STATIC EQUILIBRIUM
if the object is moving with constant velocity
DYNAMIC EQUILIBRIUM
type of contact force that resists and oppose a movement
FRICTION FORCE
the one present between two objects that are not moving with respect to each other
STATIC FRICTION
