physics 3 Flashcards
rest depends on what
it depends on the percepective a particular individual
in rest V =
v=0
in motion v =
v not equals to 0
distance is what quantity
scalar quantity
distance
total path traversed by the body
displacement
change in the direction of an objcet at a particular direction
displacement is what quantity
vector quantity
speed is what quantity
scalar quantity
speed =
distance /time
velocity =
displacement /time
avg speed =
total distance /total t
we know speed =distace / time ,so distance (s)=?
s=vt
acceleration =
change in velocity /change in time
acceleration =
vf-vi/t
slowing down of a moving object iis called
retartdation,negative acc
first eq of motion
v=u +at
seconf eq
s= ut +1l2 at^2
third eq
v^2 = u^2 +2as
at rest speed is
uniform v=constant
at motion speed is
non uniform
in a S VS T graph if the line is paralle then
then it is considered to be at rest
is a negative distance valid in SVS T GRAPH
NO IT IS NOT
is negative distance valid in case of displacemet ?
yes it is valid
in dispalcent vs time graph if the straight line is not parallel then ?
the avelocity will be uniform and not change
in S VS T GRAPH THE SLOPE INDICATES
ITS VELOCITY
CURVE or parabola EQ IN A GRAPH IS GIVEN BY
s=t^2 or y =x^2
in a velocity time graph if it is parallel to T then
UNIFORM VELOCITY STATE
