Question

Which statement is true?

A. Action and reaction forces cancel out.

B. Action and reaction forces do not cancel out because they act on different objects.

C. The reaction force is reduced by half if the object is half the size.

Answer 1

The correct statement is B. Action and reaction forces do not cancel out because they act on different objects.

Step-by-step explanation:

The correct statement is B. Action and reaction forces do not cancel out because they act on different objects. Newton's third law of motion states that for every action, there is an equal and opposite reaction. The forces exerted by the action and reaction are always equal in magnitude but act on different bodies or systems.

For example, when a person pushes a wall, the person exerts a force on the wall (action), and the wall exerts an equal and opposite force on the person (reaction). These forces do not cancel out because they are acting on different objects.

It is important to note that action and reaction forces do not cancel each other because they are separate forces acting on different systems.
