Force is the agent which causes a change in the velocity of an object and thereby to accellerate it. Inertia on he other hand is a property which relates to an intrinsic property of a body to resist any change in its state of rest or of motion (uniform or non-uniform). The term mass is used as a measure of inertia. The greater the mass of a body the less it will accellerate under the action of an applied force and vice versa.
Newton's first law of motion, is sometimes called, the law of inertia. It defines a special set of reference frames called inertial reference frames. a reference frame that moves with constant velocity with respect to the distant stars. The first postulate of Einstein's theory of relativity states:
"All the laws of physics are the same in all inertial reference frames."
This simple statement, the foundation of his special theory of relativity, was to have a profound impact on our concepts of Space and Time.

Inertia, the "Natural" State Motion
a. Straight line

Inertia, the "Natural" State Motion
a. Straight line
b. Constant speed (or at rest
Mass determines how much force is required to ?move? an object.
b. The greater the mass the greater the inertia, requiring more force to change the object?s state of motion

Inertia is the property of mass. It stays put at a place infinitely unless it is moved using an external force. Numerically inertia is measured in units of mass ie kg. Thus force comes in to play only when we move the mass using it. When we apply force it overcomes the inertia and imparts momentum(mass*velocity) to the body. The rate of change of this momentum is nothing but acceleration. so if a force F is applied and mass is m then the acceleration is F/m (in m/sec^2)

Inertia can be viewed as a qualitative description of mass.
The more mass or inertia a body has, the more force is required to, for example, stop it.
The greater the mass or inertia, the less the body will accelerate under a give force (Force / mass = acceleration)

you throw a baseball the force is you throwing it and air it hit and other factors like that and the inertia(momentum) is the movement or state at which the ball is in. the more force the more the inertia increases and the more force in will take to stop the inertia.

inertia is the current state of a object either sitting still or in motion in a straight line. An object will remain in it's current state unless acted on by another force that is greater then it's inertia to remain in its current state.

more the inertia, more is the force needed to change the state of motion or rest of the body.

Inertia is Newton's First Law of Motion... An object at rest stays at rest and an object in motion stays in motion, unless acted upon by an opposing force.
In oversimplified words, force opposes inertia... if it's moving, opposing force stops it; if it's not moving, force gets it going.
Hope this helped!

inertia is the reluctance of a moving body to stop or a still body to start moving. foce can be define by the equation: workdone(energy) = force x distance
