RECTILINEAR MOTION
o The displacement s of a body from a point O to another point P is the distance moved by the body along the straight line OP.
o Displacement, s is a vector.
o The velocity v of a body is its rate of change of displacement.
o If the time taken by a body to move through a displacement s is t, then
average velocity = final displacement, s
time taken, t
o Acceleration a is the rate of change of velocity.
o Acceleration is a vector.
