It tends to stay in that position unless some force puts that object into motion If an object is at rest… Inertia is not physical quantity and thus it does not have units The property of inertia is found from the Newton’s first law of motion Newton’s First Law of Motion An object at rest tends to stay at rest and an object in motion the same speed and in the same direction tends to stay in motion with unless acted upon by an unbalanced force RELATIONSHIP BETWEEN INERTIA AND MASS Constant wherever it is measured Base quantity Scalar quantity The SI unit of mass is kilogram (kg) Mass can influence the effects of inertia. An object with a larger mass has a larger inertia. mass inertia YOU WANT TO KNOW THE EXPLANATION ABOUT THIS??? CLICK ON THE VIDEO If the motorcycle were to abruptly stop, then the rider in motion would continue in motion. The rider would likely be propelled from the motorcycle and be hurled into the air. Once they leave the motorcycle, the rider becomes a projectile and continues in projectile-like motion. It is because of inertia. Applications of inertia Some examples of using inertia in our daily life are : The looses head of a hammer To tighten the loose head of a hammer, knock one end of the handle held vertically, on a hard surface. The hammer head will continue on its downward motion when the handle has been stopped, the top end of the handle is slotted deeper into the hammer head. The wet fur of cats and dogs. Cats and dogs dry their wet fur by shaking their body vigorously. Water droplets on the fur tend to continue in motion when the body has stopped shaking. water droplets will be separated from the fur and fall away To dislodge sticking chili sauce Chili sauce in a bottle is poured out by a quick downward movement of the bottle followed by a sudden stop. The sauce in the bottle moves with the bottle during the downward movement. When bottle is stopped, the inertia of the sauce causes it to continue on its downward
