Question

Explain why, when a person stands on a cushion, the depression is much more than when he lies down on it.

Answer 1

Hint: To solve this question we have to know that, in science and designing, the heaviness of an item is the power following up on the article because of gravity. Some standard course readings characterize weight as a vector amount, the gravitational power following up on the item. Others characterize weight as a scalar amount, the extent of the gravitational power.

Complete answer:
At the point when an individual stands on a pad, the whole weight of his body gets zeroed in on a more modest territory, subsequently delivering a bigger pressing factor. In any case, when an individual lies on a pad, the whole weight is dispersed over a bigger region, delivering a more modest pressing factor. Subsequently, the downturn in the pad is more when an individual stands than when he lies.

We also have to know about the difference between mass and weight. We can say, Mass is an exacting portrayal of the measure of issue in a molecule or object, and is autonomous of outside elements like speed, speed increase, or applied power (as long as relativistic impacts are adequately little to be disregarded). Weight has meaning just when an article having a particular mass is set in a speed increase field.

Note:We also can say, Weight (represented w) is an amount addressing the power applied on a molecule or item by a speed increase field, especially the gravitational field of the Earth at the surface. In the International System of Units (SI), weight can be communicated as far as the power, in newton s, applied on a mass in a gravitational field.
