There are two laws about inertia. The First Law has no formula. It is just a statement that says "an object will continue at constant velocity ,or at rest, until a net force acts on it". This property that requires a force to change its state of motion (or rest) is called the object's "inertia". The Second Law is a formula that describes how an object will move when a net force acts on it. The formula is F = ma. Where, F, is the force and , a , is the objects acceleration. And , m , is the objects mass, which is a measure of the object's inertia. So you could write the formula as a = F/m and in this way you see if the object's mass (inertia) is increased then in order to get the same acceleration you must increase the force. These two laws describe how an object's inertia ,or mass, resists changes in its motion.

Mass moment of inertia of a disk?

The mass moment of inertia of a disk is given by the equation I = (m * r^2) / 2, where m is the mass of the disk and r is the radius. This equation represents the resistance of the disk to rotational motion around its center.


What is the relationship between the moment of inertia times alpha in the context of rotational motion?

The relationship between the moment of inertia and angular acceleration (alpha) in rotational motion is described by the equation I, where represents the torque applied to an object, I is the moment of inertia, and is the angular acceleration. This equation shows that the torque applied to an object is directly proportional to its moment of inertia and angular acceleration.

How do you calculate inertia?

Inertia is the resistance of any object (in a physical state) to change pressed upon its current movement. It can be found by the Formula F=ma.F being force in relation to inertia, M being Mass, A is Acceleration.


How do you measure inertia of a penny?

Measuring the inertia of a penny can be done by equation or experiment. The experiment is as simple as placing the penny on a piece of cardboard on top of a cup. Flick the cardboard, which will move, and the penny just falls into the cup.


If you have increased the momentum of a moving object without increasing its inertia then you have?

Increased its velocity. By not changing its mass (inertia) and increasing its momentum, the only variable left to change is velocity in the equation momentum = mass x velocity.


What are the kinds of inertia?

There are actually 3 kinds of inertia. They are as follows : 1. Inertia of Rest 2. Inertia of Motion 3. Inertia of Direction But nowadays people consider that there are 2 kinds of inertia , inertia of rest and inertia of motion.

What is a inertia?

There is no "A inertia." Its just inertia and inertia is the measure of an objects to stay at rest or to keep moving.
