Reynolds number represents the ratio of inertial force to viscous force.

Mass is called as transnational inertia of body.

According to Newton's laws of motion, an object with more mass requires more force to change the current state. Since, a cricket ball is heavier than a tennis ball, therefore, less force is required to start motion in tennis ball than in cricket ball.

Inertia is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. It is the tendency of objects to keep moving in a straight line at constant velocity.

The mass can be described as inertia of object which resist its changes in state of motion and rest. Hence correct answer is B.

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Galileo Galilei first proposed the concept of inertia. Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

Factors on which inertia of a body depend are:
(1) Mass
(2) Axis of rotation

Mass of a body is the measure of its inertia i.e., more the mass, more is the inertia. Keeping this in mind:
Five rupees coin has more inertia.

A stone.
Inertia is associated with mass. Objects having more mass have more inertia.

Yes, when external unbalanced force on an object is zero, the object can travel with a non-zero velocity. Such a motion will be a uniform motion. The conditions for this are:
(i) Magnitude of velocity must be constant.
(ii) Direction of velocity must be constant i.e., it travels in a straight line without change in direction.

Inertia is a physical property that offers resistance to change in the state of motion of an object i.e an object tends to remain in its initial state of motion when no external force is applied to it.

The concept of Inertial force is mainly used as a pseudo force in case of accelerating frames of reference.

The object having the greatest mass has the greatest inertia because more force is required to change the initial state of the object.

Inertia has direct dependence on mass.

Mass of body is translation inertia. So, more mass means more inertia. (heavier body difficult to move)

Mass is a translation inertia of body.

It’s because of inertia, which is simply the tendency of any body to continue on whatever path it’s travelling unless acted on by an external force. For a standing passenger, his/her body will tend to continue along the straight line route the bus was travelling before the sharp turn. As the passenger’s feet are fairly firmly located to the floor of the bus when it turns, a force will act upon the passenger’s feet accelerating them towards the centre of the turn. 

Mass is the count of inertia. 

Inertia is the quality in matter (matter is anything you can touch) that lets it stay still if it is still, or keeps it moving if it is moving.

The property of a body to resist any change in its state of rest or of motion in a straight line is called its inertia.

Inertia is the physical property of a body to resist any change in its state of rest or of uniform motion.

The object having more mass has more inertia and vice-versa.As object X has more mass than Y, thus X has more inertia.

Inertia is the property of matter which offers resistance of any physical object to any change in its state of motion including changes to its speed and direction or the state of rest.

When the bike stops suddenly, the back seater will get a jerk in a forward direction due to inertia of motion as the bike is stopped the body in contact with the bike will also try to stop but the upper portion of the body will still try to maintain its motion.

Mass of the object is the measure of its inertia in the sense that greater the mass of the object, greater will be its inertia and vice-versa.

Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

Law of inertia states that present state (in motion or stationary) of a body does not change until an external force is applied on it .

Inertia of motion depend upon mass

$Force=mass*\dfrac{momentum}{time}$

Inertia of an object is the tendency of the object to resist change in  motion. The inertia is directly dependent on the mass of the body. 
Inertia resist any change in its state of motion and is of three types:

1. Inertia of rest
2. Inertia of motion
3. Inertia of direction

When horse stop suddenly rider falls due to inertia as when the horse is in motion rider also is in motion and when horse stop suddenly there is no external force acting on the ride to stop its motion therefore  rider falls forward.

Yes inertia means resistance to the charge of state

If we see by Newton second law of motion.

A coin tossed vertically by a passenger sitting in a train that is moving with a uniform velocity, still returns to his palm, it happens due to the phenomenon of inertia as the person and coin in his hand both are in uniform motion with the train.
