Rectilinear Motion

Definitions

• • Rectilinear motion: position, velocity, and acceleration of a particle as it moves along a straight line

  • Curvilinear motion: position, velocity, and acceleration of a particle as it moves along a curved line

Curvilinear motion

Rectilinear Motion Equations

• v = u + at

• v² = u² + 2as

• s = ut + (12) at²

u: initial velocity (m/s)

v: final velocity (m/s)

a: acceleration (ms^-2)

s: displacement (m)

^{MEMORISE THESE EQUATIONS!!!}

When answering questions, find out what values you have and write them down. Then decide which equation you need and fill in all the values you have.
