Rectilinear Motion

Rectilinear Motion

1. Rectilinear Motion is motion along a straight path.

2. Equations

   • s = vt
   • a = (v - u) / t
   • v = u + at
   • s = 1/2 * t (u + v)
   • s= ut + 1/2 * at^2
   • v^2 = u^2 + 2as

3. Definitions

   • Instantaneous Velocity - The velocity of an object in an instant.
   • Average Velocity - Distance travelled divided by time.
   • Acceleration is change in velocity over time.

4. Every object accelerates downwards (on Earth) at 9.81ms^-2

5. Remember SUVAT!
