Travelling on the Downtown Line
Acceleration
SI units : m/s^2
Definition: Acceleration is the rate of change in velocity with respect to time.
Formula for Acceleration = v = x/t
v0 = initial velocity
v = final velocity
t = time
A = acceleration
Displacement
SI units : m
Definition: Displacement is the vector quantity and it is defined as the distance measured from a reference point to the final position of a point.
Formula for Displacement = v = ds/dt
s = displacement
t = time
v = velocity
Velocity
SI units: m/s
Formula for Velocity = v = ds/dt
s = displacement
t = time
v = velocity
Definition: Velocity is a vector quantity and it is defined as the rate of change of displacement.
For constant velocity, Total displacement = Velocity x Time taken = Area under the graph
Finding max/min value: The gradient on a displacement-time graph is velocity. The gradient on a velocity-time graph is acceleration.
Uniform motion: A motion is called uniform motion when the acceleration is constant.
Displacement-time graph is a plot of the displacement against time.
