already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Inertia can be defined in three ways:
  • the apparent resistance to force
  • the resistance of an object to a change in its motion (or lack thereof)
  • the tendency of an object at rest to stay at rest, and for an object in motion to remain in motion.

These are all really saying the same thing. An object with mass requires force
to change its motion, or to start moving from a stationary position. Once the
force is applied, the object will move at a constant velocity until affected by
another force. Inertia is proportional to the mass of any object - the greater
the mass, the greater its inertia.

Two Examples
The inertia of an object resists a change in its motion. That is why seat belts
are used in cars. When the car turns, your body is still trying to continue in
the original direction. If the car suddenly stops, your body still wants to
continue forward.
Inertia also tries to keep a stationary object stationary. If you have to push a
broken-down car from the road, there is a tendency to resist this movement.
And a heavier car is harder to push than a lighter car, even with the same
Inertia is the tendency of an object at rest to remain at rest until some force
acts to move it; also, the tendency of a moving object to continue moving
until something acts to stop it.

Inertia is the property of all matter by which it remains in constant, uniform
motion until acted upon by an external force.
Inertia is a measure of mass.

What is inertia how does it affect the why an object moves?

Inertia is the tendency of an object to resist a change in its motion. Objects with more mass have more inertia. The more mass an object has the harder it is to change its mot

What is inertia at rest?

the inherent property of a body by a virtue of which it can't change its position of rest is called inertia at rest

What does inertia do?

Inertia is the resistance of an object to change it state of rest or motion. when you are standing in a moving bus and it suddenly stops you tend to fall backward. This is du

What is inertia used for?

  Inertia is not really a tool to be used... Inertia is basically an object's resistance to being moved. It stems from Newton's 2nd law of motion, which states that the

What is inertia refers to?

Inertia refers to a lack of motion in a body. Inertia can also mean  that there is resistency by a body to change direction and/or  speed.

What is inertia of rest?

  Inertia is the characteristic of matter by which a body at rest remains at rest, and a moving body remains in motion, until/unless some unbalanced force acts upon the bo

What is inertia dependent upon?

Inertia is dependent on the mass of the object being considered, and sometimes by its momentum - depending on how we are using the term. Recall that inertia is the resistance

What is inertia in law of motions?

The natural tendency of an object to not move (if it wasn't moving), or to keep moving (if it was moving). Inertia is the characteristic that a object will want to stay at res

What is inertia define it?

Inertia is the force push against something when another thing is in motion. For example if I threw a ball force is put on the ball and with the help of gravity the ball comes

What is inertia and what is the dimension of inertia?

inertia comes from the word iner, meaning lazy or idle. hence inertia is the tendency of a body to remain unchanged. it is also the tendency that opposes any change in the sta

What is Inertia at motion?

Apparent or perceived resistance to acceleration in a frictionless environment. Force= mass x acceleration, so you need a greater force for a greater mass to get a given accel

What is inertia of motion?

Inertia is the tendency of an object to resist a change in motion. It depends upon the objects mass. If an object has more mass, it is more difficult to get it moving. Once
