True or False

___1.Normal force is that exerted by a surface on an object that is resting on it and is always parallel to that surface.
___2.In the law of action and reaction, the pairs of forces act on different objects.
___3.Newton's second law states that the force applied to an object is inversely proportional to the acceleration that is applied to this object due to this force.

Answer #1

1) Normal force is the force exerted by a surface on an object that is resting on it and is always perpendicular to that surface.

So the statement is false.

2) Action and reaction never cancels each other because the forces are acting on different objects

So the statement is true.

3) According to Newton's second law the acceleration of an object produced by an applied force is directly proportional to the applied force.

So the statement is false.
