Kinematics Flashcards
Distance is…
total length covered by a moving object regardless of the direction.
Scalar quantity.
Displacement is…
total length covered by a moving object in a specific direction
Vector quantity.
Speed is…
rate change of distance with respect to time.
unit: ms^-1
Speed is… (what quantity)?
Scalar quantity
If Speed changing, get average speed. formula?
average speed = total distance / period of time
Velocity is…
rate change of displacement with respect to time
unit: ms^-1
velocity is… (what quantity)?
Vector quantity
Unit of velocity?
ms^-1
Unit of speed?
ms^-1
formula of velocity?
velocity (v) = change in displacement (△s) / time taken (t)
Acceleration is…
rate change of velocity with respect to time
unit: ms^-2
formula of acceleration?
accl (a) + change in velocity (△v) / time taken (t)
a= v-u / t
