Forces on an object are either balanced or unbalanced

3. Force
A force is defined as an action on an object that affects its motion (or lack of motion).
The action is often called a push or pull. The push can come from direct contact, like when objects collide or from a force field like magnetism. The pull seems to only come from a field at a distance, like gravity or magnetism.
The action from a force can cause an object to move, or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it can be said that a force on an object results in the acceleration of an object.

4. Balanced/Unbalanced Forces
Balanced if equal in force, but opposite in direction. The object’s motion will NOT change.
Unbalanced if not equal in force. The motion WILL change.

5. Physics of Flight

7. Friction
Friction is a force that resists motion between two touching surfaces.
It always acts opposite to the direction of the motion.

8. Magnetism
Magnetism is a force of attraction or repulsion that acts at a distance. It is due to a magnetic field, which is caused by moving electrically charged particles or is inherent in magnetic objects such as a magnet.
A magnet is an object that exhibits a strong magnetic field and will attract materials like iron to it.
Magnets have two poles, called the north (N) and south (S) poles. Two magnets will be attracted by their opposite poles, and each will repel the like pole of the other magnet.
