Question 1

What is gravity?

Accepted Answer

Gravity is a force that pulls things towards each other. It’s why things fall to the ground when you drop them.

Question 2

Who discovered gravity?

Accepted Answer

Sir Isaac Newton is famous for discovering gravity. He came up with the idea after seeing an apple fall from a tree.

Question 3

Why do we stay on the ground instead of floating away?

Accepted Answer

We stay on the ground because gravity pulls us towards Earth. Without gravity, we would float into space!

Question 4

Why do things fall down?

Accepted Answer

Things fall down because gravity is pulling them towards the Earth. Gravity pulls everything down to the ground.

Question 5

Does gravity work in space?

Accepted Answer

Yes, gravity works in space too. It keeps planets, like Earth, in orbit around the sun.

Question 6

Do the moon and the Earth have the same gravity?

Accepted Answer

The moon has less gravity than Earth. That’s why astronauts on the moon can jump so high.

Question 7

What would happen if there was no gravity?

Accepted Answer

Without gravity, everything would float away into space. We couldn’t walk, and nothing would stay in place.

Question 8

Does gravity affect light?

Accepted Answer

Yes, gravity can bend light. This is called gravitational lensing and makes light look like it’s bending around large objects like stars.

Question 9

Do heavier things fall faster because of gravity?

Accepted Answer

No, heavier things don’t fall faster. Gravity pulls everything down at the same speed unless other forces, like air, slow them down.

Question 10

Can we see gravity?

Accepted Answer

We can’t see gravity, but we can see its effects. When you drop a ball and it falls, that's gravity at work.

Question 11

How does gravity help us in everyday life?

Accepted Answer

Gravity helps us keep our feet on the ground and makes things fall when we drop them. It also helps water flow down rivers.

Question 12

Why does the Earth orbit the Sun?

Accepted Answer

The Earth orbits the Sun because the Sun’s gravity pulls on the Earth while Earth tries to move in a straight line. This makes it go in circles around the Sun.

Question 13

Why do astronauts float in space?

Accepted Answer

Astronauts float in space because they are in orbit, which means they are falling around the Earth. There is still gravity, but they don’t feel it like we do on Earth.

Question 14

Why do we feel heavier when we go up a hill?

Accepted Answer

We don’t actually weigh more, but going uphill is harder because gravity pulls us back down. It takes more effort to move against gravity.

Question 15

Do animals feel gravity too?

Accepted Answer

Yes, animals feel gravity just like we do. It helps them walk, run, and stay on the ground.

Question 16

How does gravity help planets stay in their orbits?

Accepted Answer

Gravity keeps planets in their orbits by pulling them towards the sun. This constant pull balances with their forward motion, so they don’t fly away.

Question 17

Is there gravity on other planets?

Accepted Answer

Yes, there is gravity on other planets. However, it might be stronger or weaker compared to Earth, depending on the planet’s size.

Question 18

What role does gravity play in the tides?

Accepted Answer

Gravity from the Moon and Sun pulls on Earth’s oceans, causing high and low tides. The water bulges where the pull is strongest.

Question 19

Why don't airplanes fall even though gravity pulls them down?

Accepted Answer

Airplanes stay up because their wings create lift, which works against gravity. The engines provide thrust to move them forward.

Question 20

Does the Sun have gravity?

Accepted Answer

Yes, the Sun has gravity, and it’s really strong. Its gravity keeps all the planets in our solar system orbiting around it.
