Question 4.10

Part A = The magnitude of the force of the brick on the glass is equal to the magnitude of the force of the glass on the brick.

Solution Below:

Part A

A brick hits a glass window. The brick breaks the glass, so:

  • The magnitude of the force of the brick on the glass is greater than the magnitude of the force of the glass on the brick.
  • The magnitude of the force of the brick on the glass is equal to the magnitude of the force of the glass on the brick.
  • The magnitude of the force of the brick on the glass is smaller than the magnitude of the force of the glass on the brick.
  • None of the preceding

Newton’s 3rd Law says that for every action there is an equal and opposite reaction. So options A and C are incorrect. Option B is correct according to Newton’s 3rd law (equal and opposite forces). So option D is wrong and:

The magnitude of the force of the brick on the glass is equal to the magnitude of the force of the glass on the brick.
