Linear motion Flashcards
state the meaning of distance
is the actual ground covered by a moving body
what is displacement
is the distance covered by a moving body in a certain direction
what is speed
the distance covered by a body per unit time
what is average speed and instanteneous speed
a speed obtained by the timing of motion of a body over a very short time interval
what is velocity
is the change of displacement of a body per unit time
what is average velocity
total displacement divided by total time
what is acceleration
is the rate of change of velocity
what is a ticker tape timer ?
is a device used to study motion of an object
in a ticker time what shows that the tape is moving slowly
if the dots are very close
what shows that the ticker timer is moving fast
if the dots are far apart
what shows that the ticker timer is accelerating ?
if the distance between the dots are increasing
what shows that the ticker timer is decelerating ?
if the distance between the dots decreases
how is total time given
total spaces between the dots minus 1
what is the formula of getting the accelration due to gravity
g =4pie squared times length divided by t which is time
draw a graph showing displacement time graph of a uniform body
their is a straigh line
