Inertia is the resistance of any physical object to any change in its state of motion (this includes changes to its speed, direction or state of rest). It is the tendency of objects to keep moving in a straight line at constant velocity. Basically in simple terms, when an object is sitting still or moving and not speeding up or slowing down but staying in a constant velocity, it will stay that way as long as no other forces are applied to it. An excellent example of this would be placing a can on a table. A normal can with no special properties as same with the table. After the can is placed it will just sit there and not move because there are no forces being acted upon …show more content…
There are four types of forces regularely seen in force diagrams (force diagrams are diagrams showing all the forces being applied to an object). These four forces are; the normal force, the applied force, the friction force, and the gravity force. The applied force is a force being applied to the object such as a hand pushing a box, the hand would be the applied force. The applied force is written all over Newton's Second Law because the law basically states that if something were to push an object it would be described as the mass and the acceleration combined through
