Newtown’s thirds law of motion

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

  Newton's third law of motion
• How do the forces exerted by two interacting objects behave according to Newton's third law?

  They are equal and opposite
• What is recommended to learn exactly for the exam regarding Newton's third law?

  The law as stated in the video
• Why might Newton's third law seem tricky?

  It involves understanding interactions between objects
• What happens when a man in a canoe uses a paddle?

  • The man pushes on the water
  • The water pushes back on the paddle
  • Forces are equal in magnitude, opposite in direction
• What occurs when a skateboarder jumps off a skateboard?

  • The skateboarder applies a push force on the skateboard
  • The skateboard moves to the right
  • The skateboard pushes back on the skateboarder
  • The skateboarder moves to the left
• How does a rocket's firing demonstrate Newton's third law?

  • Chemical reaction produces downward push on exhaust gases
  • Exhaust gases exert equal force upwards on the rocket
  • Forces are equal in magnitude, opposite in direction
• What happens when a car is driving?

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

  In the revision workbook
• What is the relationship between the forces exerted by the wheel and the road when a car is driving?

  They are equal in magnitude but opposite in direction
