The correct answer is velocity.

Key Points 

CONCEPT:

  • Velocity/ speed: The rate of change of displacement/distance of a body is called the velocity/speed of that body.
    • Velocity is a vector quantity that has both magnitudes as well as direction.
  • Acceleration: The rate of change of velocity is called the acceleration of the body.
    • Acceleration is also a vector quantity.
  • The slope of any velocity-time graph gives an acceleration of the body.
  • Displacement: The minimum path length between two points is called displacement.
  • Distance: The total path length between two points is called distance.

Explanation:

From the above explanation, we can see that, 

  • Acceleration is the rate of change of velocity
  • In other words, it is the ratio of change in velocity and time taken
  • It has SI units of m/s2 and is also the derivative of velocity

Additional Information

Name Description
Displacement The shortest distance between two points
Speed Distance travelled per unit time
Jerk Rate of change of acceleration
