Kinematics

• Instantaneous velocity is the velocity at a particular point in time
• Instantaneous velocity is the velocity at a particular point in time

  it is the gradient of the tangent in a displacement/time graph
• Acceleration is the rate of change of velocity

  Instant acceleration = gradient of tangent

  Area under a velocity/time graph = displacement
• Distance/time graph = speed is the gradient

  Displacement/ time graph = velocity is the gradient

  Velocity/time graph = Acceleration is the gradient
• Define average speed and give the equation

  Average Speed = Total distance/Total time

  Speed is the rate of change of distance
• Define average velocity and give the equation

  average velocity = total displacement/ total time

  Velocity is the rate of change of displacement
• Define acceleration and give an equation

  acceleration = change in velocity/change in time

  acceleration is the rate of change in velocity
• Define Instantaneous velocity

  Instantaneous velocity is the velocity at a particular point in time it is the gradient of the tangent in a displacement/time graph
• Instantaneous acceleration

  The gradient of the tangent in a velocity/ time graph
• What is the area under a velocity time graph

  Displacement
