acceleration 2

• Velocity


  The speed of an object in a particular direction
• Acceleration


  The rate of change of velocity
• Calculating acceleration


  Acceleration = Change in velocity / Time
• Constant rate acceleration


  When an object accelerates at a fixed rate
• This equation is more likely to appear on the higher paper than the foundation paper
• Acceleration due to gravity

  9.8 m/s^2
• Air resistance


  Upward force of friction with air particles
• Terminal velocity


  The constant velocity reached when the force of air resistance balances the force of gravity
• Terminal velocity depends on the object's shape and the fluid it is falling through
