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
tires.
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 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 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 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 related to?

Inertia is a body's resistance to moving, or to change velocity once under motion. It is a function of mass and velocity.  Inertia can also be described as a body's tendanc

16 What is inertia?

Inertia is the tendency of an object in motion to stay in motion until acted upon by a force.

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

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 selling?

  It is the practice of supplying unordered items seeking payment for them. This act is totally prohibited by law.

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 force?

It is important to learn many things in physics. Inertia Force is  defined as a force opposite to an accelerating force acting on a  body, and equal to the product of the ac

What is inertia torque?

Inertia torque an imaginary torque, which when applied upon a rigid body, brings it in an equilibrium position. Its magnitude is equal to accelerating couple, but opposite in
In Science

What is inertia mean?

is the resistance of any physical object to any change in its state  of motion, including changes to its speed and direction.
