6thsci- Ch 15 Les. 2 Gravity Affect Objects

Explanation
The explanation for the given correct answer is that according to Newton's law of universal gravitation, every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This gravitational force is always present and acts on all objects, causing them to be attracted to each other. Therefore, it can be concluded that every object is indeed attracted to other objects by gravitational force, making the statement true.

Explanation
Gravitational force is directly proportional to the masses of the objects involved. Therefore, when the masses of the objects are large, the gravitational force between them will also be greater. This is because larger masses have a stronger gravitational pull, resulting in a stronger force of attraction between them.

Explanation
As objects move closer to each other, the gravitational force between them becomes larger. This is because the force of gravity is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between them. When the distance decreases, the force of gravity increases. Therefore, as objects move closer to each other, the gravitational force becomes larger.

Explanation
Weight is a force that is measured in newtons. Newton is the standard unit of force in the International System of Units (SI). It is named after Sir Isaac Newton and is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. Therefore, weight can be measured in newtons, which is the correct answer.

Explanation
The Moon's gravity is approximately 1/6th of Earth's gravity. This means that an object on the Moon weighs only about 1/6th of what it would weigh on Earth. This is due to the Moon's smaller mass and size compared to Earth, resulting in weaker gravitational force.

Explanation
A rise or fall in water level near the ocean's shore is referred to as a tide. Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans. As the moon orbits the Earth, it creates a gravitational force that causes the ocean water to bulge towards it, creating a high tide. When the moon is on the opposite side of the Earth, it creates a low tide. The sun also has a smaller influence on tides. Tides occur twice a day and can vary in intensity depending on factors such as the phase of the moon and the geography of the coastline.

Explanation
The Moon's gravitational pull creates a tidal force on Earth, causing the ocean waters to bulge towards the Moon. As the Earth rotates, this bulge creates high tides on the side of the Earth facing the Moon and on the opposite side. The areas in between experience low tides. Therefore, the Moon's gravity is responsible for the tides in Earth's oceans.

Explanation
Coastal areas around the world typically experience two low and two high tides each day. This is due to the gravitational pull of the moon and the sun on the Earth's oceans. As the Earth rotates, different parts of the coastline are exposed to the gravitational forces, causing the tides to rise and fall. The two high tides occur approximately 12 hours apart, as do the two low tides. Therefore, the correct answer is 2.

Explanation
As Earth spins on its axis, the part of Earth facing the Moon experiences a high tide. This is because the Moon's gravitational force pulls on the water on Earth, causing it to bulge towards the Moon. As the Earth rotates, different parts of the planet come under the influence of the Moon's gravitational pull, resulting in the occurrence of high tides in those areas.

Explanation
Isaac is the correct answer because Isaac Newton is a well-known physicist and mathematician who made significant contributions to the fields of physics and mathematics. He is famous for formulating the laws of motion and the law of universal gravitation. So, his first name is Isaac.
