Newtons 3rd law

• What does Newton's third law state about the forces two objects exert on each other?

  The forces are equal and opposite.
• What does the term "equal" refer to in Newton's third law?

  It refers to the magnitude of the two forces.
• What does the term "opposite" refer to in Newton's third law?

  It refers to the direction of the two forces.
• If you push a box with a force of 100 newtons, what force does the box exert on you?

  100 newtons in the opposite direction.
• What is the force that the box exerts on you called?

  Normal contact force.
• What determines whether you or the box will move when you push it?

  The mass of the box and the force applied.
• What happens when you push a small box?

  The box is likely to move because it has a much lower mass.
• What happens when you push a large box?

  The box may not move at all, and you might be pushed backwards instead.
• How is pushing off a wall similar to pushing a box?

  Both involve exerting a force that results in movement of the person or object.
• What can happen when pushing a medium-sized box?

  You might get pushed backwards a little, and the box might still go forwards a bit.
• What is the equation that relates force, mass, and acceleration?

  $F =$$m a$
• How can you rearrange the equation $F =$$m a$ to find acceleration?


  $a =$$\frac{F}{m}$
• What is required for an object to be accelerated and move?

  You need either a high force or a small mass.
• What generally happens when a smaller object is pushed?

  The smaller object will generally move most.
• What are the key concepts of Newton's third law of motion?

  • Forces between two objects are equal and opposite.
  • Equal refers to the magnitude of the forces.
  • Opposite refers to the direction of the forces.
• What is the relationship between force, mass, and acceleration according to Newton's second law?

  • The equation is $F =$$m a$.
  • Rearranged to find acceleration: $a =$$\frac{F}{m}$.
  • For movement, either a high force or a small mass is needed.
