KINEMATICS Flashcards
definition of distance
total length covered by moving object
direction of motion DOES NOT matter
definition of displacement
straight line distance covered by moving object regardless of path taken
direction needs to be SPECIFIED
example of displacement
start point to end point got shortcut(straight line)
what is speed
the change in distance per unit time
what is velocity
change in displacement per unit time
speed formula
speed = d/t
formula for velocity
v = displacement/ time
what quantity is speed
scalar quantity
what quantity is velocity
it is a vector quantity
si unit for speed
m/s
si unit for velocity
m/s
definition of acceleration
change in velocity per unit time
what quantity is acceleration
vector
si unit for acceleration
m/s2(metre per second per second)
formula for acceleration
v-u over t
