Newton’s Third Law

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

  Newton's third law of motion
• What do Newton's first and second laws of motion indicate about their complexity?

  They are fairly straightforward
• How does Newton's third law of motion describe the forces between two interacting objects?

  They are equal and opposite
• Why is it recommended to learn Newton's third law exactly as stated?

  It may be required for exam answers
• What can make Newton's third law seem tricky?

  Its conceptual nature and application
• How does a skateboarder demonstrate Newton's third law?

  • The skateboarder pushes off the skateboard
  • The skateboard moves to the right
  • The skateboard pushes back on the skateboarder
  • The skateboarder moves to the left
• What happens when a rocket fires according to Newton's third law?

  • The rocket produces a downward push on exhaust gases
  • The exhaust gases exert an equal upward force on the rocket
  • Forces are equal in magnitude and opposite in direction
• How does a car's wheel demonstrate Newton's third law while driving?

  • The wheel exerts a backward force on the road
  • The road exerts a forward force on the wheel
  • Forces are equal in magnitude and opposite in direction
• Where can you find more questions on Newton's third law?

  In the revision workbook
• What is the relationship between the forces exerted by two objects according to Newton's third law?

  They are equal in magnitude and opposite in direction
