  1. Balanced forces are equal in size and opposite in direction, resulting in no change in motion (e.g., a book resting on a table). Unbalanced forces are not equal, causing a change in motion (e.g., pushing a toy car).

  2. When forces are balanced, the object's motion remains unchanged, either staying still or moving at a constant speed.

  3. A ship maintains forward motion due to inertia and propulsion from its engines overcoming friction and drag.

  4. A ship with a velocity of zero remains stationary until acted upon by an external force.

  5. Net force is the overall force acting on an object, calculated by summing all individual forces; it determines the object's motion.

  6. To diagram forces, represent each force as an arrow; the length shows magnitude and direction indicates the force's application.

  7. To interpret force diagrams, assess the direction and length of arrows to understand how forces interact and their resultant effect on motion.

Effects of gravitational acceleration include the constant force pulling objects toward the Earth's center, influencing their weight and causing them to fall when unsupported.
