Newton's Laws of Motion

• What does Newton's third law state about forces between two objects?

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

  The magnitude of the two forces.
• What does the "opposite" in Newton's third law refer 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 normal contact force?

  The force the box exerts back on you.
• What determines which object will move when two objects interact?

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

  The box is likely to move.
• What happens if you push a large box?

  You might be pushed backwards instead.
• How does pushing off a wall relate to Newton's third law?

  You push the wall, and you move back.
• What happens when you jump off the ground?

  You push down, and you move up.
• What occurs if the box is medium-sized when pushed?

  You might move back a little, box moves forward.
• What is the equation for Newton's second law?

  $F =$$m \cdot a$
• How can you rearrange Newton's second law to find acceleration?

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

  A high force or a small mass.
• Why does a smaller object generally move more easily?

  It has a smaller mass compared to the force.
• What are the implications of Newton's third law in interactions?

  • Forces between two objects are equal and opposite.
  • The direction of forces matters.
  • The mass of objects affects movement.
• How does mass influence movement in Newton's third law?

  • Smaller mass: more likely to move.
  • Larger mass: less likely to move.
  • Medium mass: may result in partial movement.
