A push or pull in any particular direction!!!
Contact and Non-Contact
Where two or more objects came into contact with each other, changing their direction.
A Non-Contact Force:
This is when the motion or shape of an object changes without touching another object.
Examples (sitting in a chair)
• The two forces that are acting on us are balanced. They cancel each other out which means there is no overall force on us when sitting in a chair unless the forces are unbalanced ( the body being to heavy for the chair pulling us faster and harder because of weight).
