Kinematics
formulae for constant acceleration
u is initial velocity.
v is final velocity
a is acceleration
s is displacement
t is time
On a velocity-time graph
gradient represents acceleration
area under the graph represents displacement
horizontal line means constant velocity
sloping line means changing velocity
Definitions
Displacements
SI unit is [m]
denoted by s
vector quantity
it is the distance measured from a reference from a reference point to the final position of a point
Scalar vs Vectors
scalar only have magnitude
vector have both magnitude and direction
Velocity
SI unit is [m/s]
denoted by v
vector quantity
it is the rate of change of displacement
instantaneous velocity (velocity at a specific moment)
average velocity (total displacement divided by time)
Acceleration
denoted by a
is the rate of change of velocity with respect to time.
SI unit is [m/s^2]
Acceleration
positive vs negative acceleration (deceleration)
uniform acceleration (acceleration remains constant)
