Acceleration with time graphs

• Acceleration 


  Rate of change in velocity
• Negative acceleration 


  Deceleration
• U is initial velocity

  V is final velocity
• Formula for acceleration 


  v-u/t
• What does a distance-time graph show?

  How the distance travelled by an object changes over time
• Distance is on the y-axis

  Time is on the x-axis
• How do you find speed on a distance-time graph?

  Gradient of line at particular point
• Velocity-time graph?


  Shows how the velocity of an object changes over time
• How do you find exact acceleration of an object from a velocity time-graph

  Gradient of line at particular point
