Answer

Brief Explanations:

  • For the first statement: Forces in the same direction add up, not cancel. So it's false.
  • For the second statement: According to Newton's second law (F = ma), if (F_{net}=0), then (a = 0). So it's true.
  • For the third statement: From (F=ma), for the same (a), larger (m) (heavier object) needs larger (F). So it's true.
  • For the fourth statement: The net force acting on an object is equal to its mass times its acceleration ((F_{net}=ma)), not all forces. So it's false.
  • For the fifth statement: Action - reaction forces (Newton's third law) act on two different objects. So it's true.
