You will learn why some objects float, while others sink. why do boats float and rocks sink readworks answer key. The denser an object is, the more gravity it has pulled it down. Yes, the data dates back to the Greek mathematician, Archimedes. So if a boat weighs 1,000 pounds (or kilograms), it will sink into the water until it has displaced 1,000 pounds (or kilograms) of water. power bi dynamic grouping based on slicer. In simple words, any boat that floats in the water mainly because the amount of water displaced by the boat creates an upward pressure. In this Student View, your highlights and annotations will not be saved, and you cannot answer questions. The force of gravity yields a. To answer an objective question based on understanding of volume, mass, density and weight. Feathers float because their density is lower than that. So, in other words, an object will float if it weighs less than the amount of water. The strength of this force depends on the object’s mass (weight) — the more massive an object the stronger the downward gravitational force will be. Why do Ship Float? Reason 1: Archimedes Principle You must have known of the mysterious force called gravity that pulls everything down towards the earth (Bottom surface). Collect all the weights that caused the small boat to sink. Improve your students' reading comprehension with ReadWorks. Why do boats float and rocks sink Readworks? The gravitational force is determined by the object’s weight, and the buoyancy force is determined by the weight of the water displaced by the object when it is placed in water. Explanation: Two primary forces act on a body placed in water.
