Have you ever pondered why things drop down and not up?
Why do you arrive back on the ground once you hop?
Or why the Moon doesnt fair fly absent from Earth?
The reply is one capable constrain of nature called gravity.
Gravity is undetectable, but it is continuously working. You cant see it, but you’ll be able feel it. Its the reason why you remain on the ground and dont coast into space like an astronaut!
Lets investigate this astonishing constrain together in a straightforward and fun way.
Point 1: What Is Gravity?
Gravity is the drive that pulls things towards each other.
The biggest thing around us is Soil, and Earth has gravity.
Meaning it pulls everything towards it.
Once you toss a ball up, Soil pulls it back down.
Thats gravity at work!
Basic Example:
When you drop your pencil, it falls to the ground.
Why?
Since Earths gravity pulls it down.
Try bouncing up.
You dont keep going up like a rocket.
You come back down.
Thats gravity pulling you!
Theme 2: Who Found Gravity?
The story of gravity got to be celebrated since of a researcher named Sir Isaac Newton.
Newton Apple Story:
One day, Newton saw an apple drop from a tree.
He pondered, Why did the apple drop down and not fly sideways or float?
That made him think almost a pulling force and that how he begun considering approximately gravity.
So, we say Newton found gravity and made a difference us get it how it works.
Note: Newton didnt find gravity (it was continuously there), but he clarified it scientifically.
Theme 3: Gravity Is Everywhere!
Gravity isn’t fair on Soil.
Each protest in space has gravity even you!
The Sun has gravity.
The Moon has gravity.
Even a little marble has gravity (but exceptionally, exceptionally little).
The greater the question, the more grounded its gravity.
Example:
The Sun is exceptionally enormous, so it has solid gravity.
It keeps all the planets, counting Soil, moving around it.
The Moon has less gravity than Soil.
Thats why space explorers on the Moon can hop truly tall and feel exceptionally light!
Subject 4: How Does Gravity Work?
Gravity pulls everything towards the center of an object.
On Soil, gravity pulls you towards its center, which is why you’re feeling like you’re standing down.
If you were on another planet, gravity there would drag you toward that planets center.
Example:
If you hold a swell and let it go, it rises at to begin with.
But in the event that there’s no wind and no helium, it’ll fall down since of gravity.
Subject 5: Why Is Gravity Important?
Without gravity, life on Soil would be exceptionally bizarre!
Here are a few things gravity makes a difference us with:
Gravity makes a difference us:
Stay on the ground.
Keep discuss around the Earth.
Keep water within the seas and rivers.
Make rain drop from clouds.
Keep the Moon going around Earth.
Help planets go around the Sun.
Without gravity, wed be drifting all the time like in space!
Theme 6: What Would Happen Without Gravity?
Lets envision a world with no gravity.
What would happen?
Example:
You jump and never come back down!
Water would coast absent from your glass.
Buildings and houses wouldnt remain on the ground.
Cars, creatures, and individuals would all coast into the sky.
That sounds fun but moreover a small frightening, right?
Thats why gravity is very important.
Point 7: Gravity in Space
Space is full of gravity as well, but it works a small differently.
In space:
Gravity is weaker the more distant you go from a planet.
Astronauts feel like they are drifting because they are in free fall around Earth.
Soil and the Moon:
Earths gravity pulls on the Moon, and thats why the Moon goes around Earth.
The Moons gravity pulls on Soil as well! It makes a difference make tides within the ocean.
Subject 8: Gravity and Weight
Have you ever been on a weighing scale?
That number you see is your weight, and gravity is the reason you’ve got weight.
What is Weight?
Weight is how much gravity is pulling on your body.
On Soil, you weigh a certain amount.
On the Moon, you’d weigh less since the Moon has less gravity.
On Jupiter, you’d weigh more because Jupiter has more gravity.
So your weight can alter depending on where you’re within the universe, but your body (your mass) remains the same.
Point 9: Fun Tests with Gravity
Lets attempt many basic tests to get it gravity better.
Try This!
1. Drop two things a ball and a paper.
Which one falls faster?
The ball falls speedier since the paper drifts within the air.
Try folding the paper it will drop quicker presently, similar to the ball!
Thats since discuss moderates things down, but gravity pulls everything down the same way.
2. Jump Up!
Try hopping up.
Feel how you come back down?
Thats gravity!
Hold Something and Let Go
Take a toy and let go of it.
Where does it go? Down!
Gravity pulls it to Earth.
Subject 10: Huge Truths Almost Gravity
Here are a few cool and basic realities to remember:
Gravity pulls everything towards the center of a planet or star.
The more mass an question has, the more gravity it has.
Gravity is what gives you weight.
You dont coast on Soil since gravity is pulling you down.
Isaac Newton made a difference us get it gravity.
The Moons gravity causes sea tides.
Astronauts drift in space since they are falling around Soil without hitting it.
