Speed

Speed

Distance and Displacement
1. Distance
  1. How far you have travelled
  2. A scalar quantity and only has magnitude
2. Displacement
  1. Symbol 's'
  2. A vector quantity so has magnitude and direction
  3. Can be positive or negative
Graphs
1. Speed Time Graphs
  1. Magnitude
  2. Area under the graph = distance
  3. Gradient = magnitude of acceleration
  4. Only positive values
2. Velocity Time Graphs
  1. Magnitude and direction
  2. Area under the graph = displacement
  3. Gradient = Acceleration
  4. Positive and Negative Values
Formulae
1. Average Speed = Distance/Time
2. Gradient = Change in y/Change in x
3. Acceleration = (Final velocity - Starting velocity)/Time
4. Distance = Speed x Time
