Inertia is defined as the property of any matter (physical object or a body) to continue to remain in its state of rest or uniform motion unless acted upon by an external force.
This means that an object which is motionless will continue to remain motionless unless an external force is applied on it. Also the force that will be required to move a motionless body is proportional to its mass. In common language we sometimes use the words mass and weight interchangeably. However, there is a difference between the two. The mass is actually a measure of matter contained in an object.
Inertia in moving objects means that an object that is moving in a straight line at constant speed will continue to move in the same direction and with the same speed unless an external force is applied to it. The result of applying an external force to an object in uniform motion, depending on the direction of the force applied, will be to change the speed, or direction of movement, or both.
The concept pf inertia was first introduced by Sir Issac Newton in his First Law of Motion. This law states that a body will continue to remain in its state of rest or uniform motion unless acted upon by an external force.
ok. omg!!!! i kept on trying to figure dis 1 out!!!
the other night i kept on reading and reading its' definitions 4 school. and i couldn't and couldn't figure it out!! i finally got it!!! ok. here.
~Inertia is the tendency of an object to resist a change in motion. That didn't make any sense to me, i don't know about you.
~Inertia is the quality that keeps an object keep doing what it's doing. This is my definition.
- For example: If an object is moving inertia will make it keep moving.
- Or: If an object is motionless = just stading, inertiamakes sure it will keep on standing still.
To me this helped. I understand it now. I'm in fifth grade, but i'm 12. How old are you?
Inertia is a state of no activity, or state of being stable.
