What is Gravity?

<µ¿¿µ»óº¸·¯°¡±â>

 

 

Description:

 



Gravity is an invisible force that pulls objects
toward each other, which is why things fall to the ground instead of floating
or rolling away. The Earth's strong gravity keeps objects grounded, while the
moon's weaker gravity allows astronauts to jump higher, and the sun's gravity
keeps planets in orbit around it.

F: Hi pals. Ready? Watch this. So, why didit fall
instead of float or even roll away?



F: Today, we're going to learn about gravity.



M: What is gravity?



F: Gravity is an invisible force that pulls objects.



F: A force is something that pushes or pulls
something.



F: We have gravity right here on planet Earth.



F:  Gravity is
the reason why objects fall to the ground when they get dropped or knocked
over. When you jump, gravity is the force that brings you back down to the
ground. And because the Earth is so big, ¡¦



M: ¡¦the gravity here is really strong.



F: Other places have gravity, too.



M: Gravity is a force across space.



F: For example, the moon has gravity, too.



M: But the moon is much smaller than planet Earth.



F: So, the gravity is not as strong. That's why when
astronauts jump on the moon, they jump super high, ¡¦



M: ¡¦much higher than they could if they were jumping
on planet Earth¡¦



F: ¡¦because the gravity on the moon is not as strong.
But there's one place that has the largest gravitational pull in our entire
solar system.



F: That is the sun. The sun, the energy¡¦



M: ¡¦and the center of our solar system.



F: The sun's strong gravitational pull is what keeps
our planet and all the other planets in our solar system in orbit. We orbit
around the sun because of the sun's gravity.



M: So, how long does it take to make a full lap around
the sun?



F: That's a great question, Teddy. It takes about 365
days to go all around the sun or one year.



F: So, on New Year's, we're not only celebrating a new
year, but we are celebrating another lap around the sun.

Question:

 



1. Why did the object fall instead of float or roll
away?



2. How does gravity on the moon compare to gravity on
Earth, and how does this affect how high astronauts can jump?



3. Why does the sun have the strongest gravitational
pull in our solar system, and what does this force do?​
