Linear Kinematics Flashcards
Define kinematics
Motion of bodies
Define kinetics
Relationships between motion and its causes
Define translation
Object moving through space
Define rotation
Body spinning about its own centre
Define scalar
Magnitude e.g. speed
Define vector
Magnitude and direction e.g. velocity
Define velocity
Rate of change of position
Define displacement
Change in position
How are translational kinematics shown?
Upwards and to the right is positive
Velocity equation
Δv= displacement / change in time
Define acceleration
Rate of change of velocity
Can be both positive and negative
Acceleration equation
Acceleration = Δv/ Δt
What are the 4 SUVAT equations?
v = u + at
v² = u²+2as
s = ut + ½at²
s = ½( u + v) t
What does SUVAT stand for?
s = displacement
u = initial velocity
v = final velocity
a = acceleration
t = change in time
