Two equal forces act on an object. Is this information enough to say which way the object will move? Give reasons.

Solution

No, this information is not enough. Two equal forces may or may not cause an object to move. If both the forces are acting on the same side of the object and are large enough to overcome the friction force between the object and the ground, then the object will move. If both the forces are acting on the object from the opposite directions then the object will not move as the net force on the object will become zero.

Hence, the direction of the force and value of the friction force must be defined in order to determine the movement of the object.
