Define inertia. How does it depend on mass of the object? Explain
(a)Dusting of a carpet by beating it with a stick.
(b)Removal of water from wet cloth?
Answers
Answer:
INERTIA: Tendency of an object to keep its state itself in its initial state of rest or motion.
MORE IS THE MASS, GREATER IS THE INERTIA
Explanation:
a. INERTIA OF REST. dust tendsto be in state of rest and fall off when carpet is beat.
b.INERTIA OF REST.water too trnds to be
in rest when clothes is squeezed.
Answer:
inertia and 1st law of motion are same you can consider any one All objects resist changes in their state of motion. ... 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.
(a)When a carpet is beaten with a stick, the dust comes out of it because of law of inertia.
Initially the dust particles are at rest along with the carpet. Beating the carpet with the stick makes the carpet to move but the dust particles remain at rest due to inertia at rest, thus the dust gets detached from the carpet.
(b)It blows warm air across the clothes which removes the water from the clothes, which is evaporation. ... Warm air is blown across your clothes and the water from the clothes evaporates.
