What is Mass Inertia

What is inertia:-

Inertia  is the tendency of an object to rest or stay in motion. 

If we talk about the first law, then it states that the forces acting on an object are related to the mass and motion of the object in many instances.

Definition of  Inertia

Keep a book on your desk. Does the book work? Until you move the book, until then it will remain where you place it without moving it.

Imagine a spacecraft rotating through space. When the engines stop, the spacecraft will coast through space at the same speed and in the same direction.

Inertia is in the book and the spacecraft. Inertia  is the property of an object that opposes changes in its speed.  Due to inertia , an object tends to rest at rest. An object in motion moves in a straight line at a constant speed.

What is inertia and mass inertia

First Law of Newton:-

Newton's First Law of Motion explains how  Inertia  affects moving and non-moving objects. Newton's first law states that an object will remain at rest or move at a constant speed in a straight line until it is acted upon by an unbalanced force. 

Inertia  comes from mass. Items with more mass have more  inertia. To understand inertia , imagine moving a bowling ball and a golf ball that is relaxed. The mass of a golf ball is 0.05 kg, and the weight of a bowling ball is five kg. 

Explain the Inertia

The bowling ball has 100 times more mass than the golf ball, so it  also has 100 times more  inertia.

Now ask yourself, who needs more force to move forward? If you push for the same distance. So the bowling ball gets more speed so that it can move like a golf ball. The bowling ball requires more force because the bowling ball has more inertia than the golf ball.

The  higher the inertia of an object  , the greater the force required to change its speed. According to Newton's first law, an unbalanced force is required to move the book across your desk. You could supply the force by moving the book forward.

An unbalanced force is required to change the speed or direction of the spacecraft. This force could be supplied by the engines of the spacecraft. Due to inertia , as long as something moves, an object of rest will remain at rest. 

Similarly, a moving object keeps moving at the same speed and in the same direction until something acts on it to change its speed or direction.

Efect of Inertia:-

You inertia every day  Inertia  can feel. Suppose you are riding in a car. What if the car stops suddenly? There is inertia in your body   . When the car stops, you keep going. What happens when the car moves?       Due to inertia inertia, your body wants to be relaxed when the car moves forward.

Example of inertia:-

Cars and aircraft with more  inertia  take more force to accelerate. Since  inertia  is related to mass ,   to reduce inertia you have   to reduce mass .  There is a trade-off between the mass inertia of a car or plane  and the strength of the material of the car or plane. You want strong materials, but you don't want them so heavy that it takes too much energy (fuel) to move a car or aircraft! 

Seat belts can be called 'anti-inertia' belts. A car continues to run in a straight line, even if the driver's foot is not on the gas pedal. Everyone also has inertia inside the car. They are moving at the same speed as the car.        #Inertia

Suppose you are riding in a car. The driver is suddenly forced to apply the brakes. Inertia  keeps you moving at the same speed as the car used to move. As long as nothing stops you, you will keep moving forward. This can be the car's steering wheel, dashboard or windshield. If you bump into these parts of the car, you may get hurt, unless you wear a seat belt. The seat belt stops you from moving when the car stops suddenly. Seat belts can prevent serious injuries.
