Definition of Displacement
Displacement is how far and in what direction an object has moved from its starting point, regardless of the actual path it took
Vector
Si unit : m
Displacement time graph
Area under the graph represents the change in position or displacement of an object
The gradient represent the velocity of an object
Definition of Velocity
Rate of change of an object position over time
Magnitude
Si unit : m/s
Velocity time graph
Area under the graph is the displacement
The gradient represents the acceleration
Definition of Acceleration
Rate of change of velocity
Vector
Si unit : m/s^2
Acceleration time graph
Area under the graph represents change in velocity
Gradient represents the rate of change of acceleration with respect to time
Formula
v = u + a t
sf = si + u t + 1/2
a
t^2
v^2 = u^2 + 2*a(sf – si)
