True
To change the direction of motion of an object, a net force must be acting on it. According to Newton's first law of motion, an object will remain in its state of motion (including its direction) unless acted upon by a net external force. Therefore, a net force is necessary to change the object's motion, including its direction.

**False**
An object can be at rest while still experiencing forces. For example, if a book is resting on a table, the gravitational force pulling it downward is balanced by the normal force exerted by the table pushing it upward. These forces are acting on the object, but they are in equilibrium, resulting in no net force and keeping the object at rest. Thus, the statement is false.
