## What would it be like if there were no gravity on Earth?

Just like objects and people, Earth is also attracted by the sun’s gravity. If Earth’s gravity became zero, nothing would hold it and chances are that its inner core would eventually burst in a lethal titanic explosion due to intense pressure. Earth would break into pieces that would float around space, wreaking havoc.

### What effects of gravity can we see?

Gravity not only pulls on mass but also on light. Albert Einstein discovered this principle. If you shine a flashlight upwards, the light will grow imperceptibly redder as gravity pulls it. You can’t see the change with your eyes, but scientists can measure it.

What can we do because of gravity?

Some examples of the force of gravity include:

1. The force that holds the gases in the sun.
2. The force that causes a ball you throw in the air to come down again.
3. The force that causes a car to coast downhill even when you aren’t stepping on the gas.
4. The force that causes a glass you drop to fall to the floor.

What would happen if we lost gravity?

Without gravity, humans and other objects would become weightless. If Earth suddenly lost all of its gravity, we wouldn’t just start floating. The lack of any forceful gravitational pull would turn humans – and anything else with mass, like cars and buildings – into very fast-moving tumbleweeds.

## How is gravity used in our daily lives?

Gravity is very important to our everyday lives. It is the Sun’s gravity that keeps the Earth in orbit around the Sun. Life on Earth needs the Sun’s light and warmth to survive. Gravity helps the Earth to stay just the right distance from the Sun, so it’s not too hot or too cold.

### How gravity affects things on Earth?

On Earth, gravity pulls all objects to Earth’s center. Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the only force acting on the object is gravity.
