Speed, Displacement, Velocity

Speed, Displacement, Velocity

1. Define

   • Speed
   • Average Speed
   • Constant Speed
   • Velocity
     • Average Velocity
       • Constant Velocity

2. Units

   • Time
     • Distance
   • Speed
   • Displaccement
   • Velocity

3. Experiment

   • To measure velocity

4. Recall that:

   • A metre stick, a vernier callipers, micrometer are used to measure distance
   • Distance and speed ar scalar quantiies
   • Displacement and velocity are vector quantities
   • A distance time graph for an object moving with constant velocity is a straight line and its slope is the speed

5. Formulae

   • Average Speed = Distance travelled / Time taked
   • Average Velocity =Displacement Undergone / Time taken
