Get Exploring Gravity Worksheet Answers Key

The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity. Objects with more mass have more gravity.

The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it.

What is Gravity? Every entity or object in this universe employs a gravitational force or pulls on every other object. Depending on the masses of the objects, the strength of this pull is defined. The force that keeps the moon around the earth and the planets in their respective orbit around the sun is gravity.

The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.

Answer and Explanation: The two things gravitational force depends on are the mass of the two objects that generate the gravitational force and the distance between them.

It is the weakest non-contact force in nature. It obeys the inverse square law. It is always positive in nature.

In fact, our planet isn't the only place with gravity. Every object in the universe — stars, planets, moons, even you—has gravity. Gravity is a force of attraction between all objects.

Expert-Verified Answer The force that holds the gases in the sun. It causes a ball thrown in the air to come down again. It causes a car to coast downhill even when you aren't stepping on the gas. It causes a glass you drop to fall on the floor.

Originaly defined by Newton, and refined by Einstein, gravity is essentially the natural force of attraction between any two objects. Two factors determine the magnitude of the gravitational force between two objects: (1) their masses and (2) the separation distance between them.
