Acceleration 2

• What should you be able to calculate by the end of the video?

  Velocity of an object accelerating
• How is acceleration calculated?

  Change in velocity divided by time
• Why might the acceleration equation appear more on higher papers?

  It is considered trickier than foundation material
• What is the acceleration of an object falling towards Earth?

  Approximately 9.8 meters per second squared
• What force acts on a skydiver as they fall?

  Force of gravity
• What is air resistance?

  Upward force of friction with air particles
• What happens when air resistance balances the force of gravity?

  The object stops accelerating
• What is the term for the constant velocity reached by falling objects?

  Terminal velocity
• What does terminal velocity depend on?

  The shape of the object
• What is the fluid in the case of a skydiver?

  Air
• What happens to terminal velocity in liquids compared to air?

  Similar effects occur in both fluids
• Where can you find more questions on acceleration?
