Discover Gravitational Forces and How Gravity Pulls Everything Down

Gravity is a pulling force that pulls everything toward the center of the Earth. You can feel gravity every day it is what keeps your feet on the ground and makes things fall down when you drop them.

When you drop a ball, a leaf, or a book, gravity pulls it straight down toward the ground. Gravity never pushes things up or moves them sideways it always pulls things downward.

Gravity acts on all objects heavy ones and light ones. A rock and a feather are both pulled down by gravity. The feather may fall more slowly because air slows it down, but gravity is still pulling both of them toward the ground.

Here are some great examples of gravity at work that you can see every day:

• An apple falls from a tree to the ground.
• Rain falls down from clouds to the Earth.
• You slide down a playground slide because gravity pulls you downward.
• A ball thrown into the air always comes back down.
• A skier moves down a snowy hill because gravity pulls them downhill.

Even when you throw a ball up into the air, gravity is always pulling it back down. The ball slows down, stops at its highest point, and then falls back to the ground.

Your weight is a measure of how strongly gravity pulls you down. The stronger the gravity, the more you weigh. On the Moon, gravity is much weaker than on Earth, so you would weigh less and could jump much higher!

On a planet with stronger gravity than Earth, you would feel heavier because gravity would pull on you with more force. Weight and gravity are always connected.

Without gravity, there would be no force pulling you down, so you would float up and never come back down. Objects like water, books, and even people would float freely in the air.

Astronauts in a space station far from Earth experience very weak gravity, which is why they float around inside. The farther you travel from Earth, the weaker Earth's gravitational pull becomes.

Gravity: Gravity is the force that pulls everything toward Earth's center. It is what makes objects fall down when you drop them and keeps your feet on the ground.

Force: A force is any push or pull that changes how an object moves. Gravity is a type of force specifically a pulling force.

Weight: Weight is the measure of how strongly gravity pulls an object down. A heavier object has more weight because gravity pulls on it with more force.

Pull: A pull is a force that draws objects toward something. Gravity always pulls objects downward toward the center of the Earth.

Fall: When gravity acts on an object, it falls it moves downward toward the Earth. You can see this when you drop anything from your hand.

Attract: Gravity attracts objects by pulling them toward Earth's center. This means gravity draws things closer to the ground.

Land: Objects land on a surface, like the ground or a floor, when gravity brings them all the way down. Every falling object eventually lands somewhere.

Motion: Motion describes the movement that happens when gravity or another force acts on an object. When gravity pulls a ball down, the ball is in motion.

You can see Force Strength and gravity working together in many activities. When you pour a drink, gravity pulls the liquid down into your cup. When you jump, gravity pulls you back to the ground every single time.

Think about a seesaw at the playground. The heavier friend goes down because gravity pulls harder on their side. This is a great example of how gravity affects objects with different weights.

You can also connect gravity to Motion in Materials when objects move through air or water, gravity is still pulling them downward the whole time.

Before learning about gravity, you explored Types of Motion Push, Pull, Speed, and Direction. Knowing about pushes and pulls helps you understand that gravity is a special kind of pull that always acts downward.

You also learned about Physical Properties and Observable Characteristics of Materials, which helps you notice how different objects behave when gravity acts on them. And your knowledge of Simple Machines connects here too machines like slides and ramps use gravity to help objects move.

Gravity is one of several important forces you will explore. You already learned about Magnetic Forces Attraction and Repulsion, which is another type of force. While gravity always pulls downward, magnetic forces can both attract and repel objects.

As you keep learning, you will discover Force Strength and Effects of Different Forces, which shows you how forces of different strengths change the way objects move. You will also explore Motion in Materials Movement Through Air and Water, where gravity plays a big role in how objects move through different materials.

Gravity also connects to Properties of Solids and Properties of Liquids gravity is what makes liquids flow and pour, and it affects how solid objects rest on surfaces. You can also see gravity at work when you study Weather Impact and Effects on Earth's Surface, since rain and snow fall because of gravity.

Next, you will build on what you know about gravity to understand Balanced Forces and Equal Opposing Forces and Unbalanced Forces and Net Force and Motion. You will also go deeper into Magnetic Forces Fields and Interaction, explore Work and Force Mechanical Advantage, and learn about Machine Types Levers, Pulleys, and Inclined Planes, all of which depend on your understanding of gravity and forces.
