Gradient of a Velocity-Time Graph

  • Acceleration is any change in the velocity of an object in a given time

  • As velocity is a vector quantity, this means that if the speed of an object changes, or its direction changes, then it is accelerating
    • An object that slows down tends to be described as ‘decelerating’

  • The gradient of a velocity-time graph is equal to acceleration
