Inertia is a definition of mass so an object with greater mass will have greater inertia. The mass of the engines of the airplane on their own probably have more inertia than the car. Mass is usually measured by determining the weight of the object, which is defined as the gravitational force pulling down on it.
Which of the following has greater inertia?
Inertia is the measure of the mass of the body. The greater is the mass of the body; the greater is its inertia and vice-versa. (a) The mass of a stone is more than the mass of a rubber ball for the same size. Hence, the inertia of the stone is greater than that of a rubber ball.
Which one of the following objects has the greatest inertia?
A more massive object has more inertia than a less massive object. Fast-moving objects have more inertia than slow-moving objects. An object would not have any inertia in a gravity-free environment (if there is such a place). Inertia is the tendency of all objects to resist motion and ultimately stop.
How many laws of inertia are there?
What is inertia class 9th?
Defintion: Inertia is a property or tendency of every object to resist any change in its state of rest or of uniform Force and Laws of Motion. It is measured by the mass of an object. The heavier the object, the greater will be its inertia.
What is the first law of motion class 9?
The first law of motion implies that things cannot start, stop, or change direction all by themselves. It requires some force from the outside to cause such a change. This property of massive bodies to resist changes in their state of motion is called inertia.
Why do we fall sick?
Whenever the normal working of our body system gets disturbed, we feel sick. It can happen when a bacterium, virus, etc, enters our body or because of unhealthy living practices like lack of exercise or intake of drugs/excessive sugar/salt. There are two major kinds of diseases: infectious and non-infectious.
Why my immune system is weak?
Not enough protein in your diet can weaken your immune system. Your body also produces proteins when you sleep that help your body fight infection. For this reason, lack of sleep reduces your immune defenses. Cancers and chemotherapy drugs can also reduce your immunity.
Where do we go when we fall sick?
If you can’t get in to see your doctor and you want to be seen in person, a convenience clinic (such as the ones inside retail stores, supermarkets or pharmacies), or an urgent care clinic (usually near your primary care clinic) is your next best option.
