Speed

1. Speed is the rate of change in distance. It is a measure of how fast the distance change in a movement.
2. Speed is a scalar quantity.
3. The SI unit of speed is m/s (metre per second) Equation of Speed Velocity
1. Velocity is define as the rate of displacement change. It is the measure of how fast the displacement change of a moving object.
2. Velocity is a vector quantity.
3. The unit of displacemnet is m/s (metre per second) Equation of velocity Positive or Negative Sign of Velocity
1. In velocity, the positive/negative sign indicates direction.
2. You can take any direction as positive and the opposite as negative.
3. For a linear motion, normally we take the motion to the right as positive and hence the motion to the left as negative.
