Why Do Things Fall Down?

[thud] Drop a ball — it falls right down [thud] Drop a cup — it hits the ground Drop a book, a shoe, a spoon Everything comes down real soon

Why do things fall down, not up? Why does milk fall from a cup? Why do things fall down, not up? Let me tell you what is up!

Gravity! Gravity! Pulling you and pulling me! Gravity! Gravity! Pulling everything we see!

The Earth is big, so big you see It pulls on you, it pulls on me It pulls on birds and pulls on rain It pulls on every ball and plane

Gravity! Gravity! Pulling you and pulling me! Gravity! Gravity! Pulling everything we see!

Everything with mass inside Has a pull it cannot hide The bigger you are, the stronger the pull The Earth is BIG — its pull is full!

How do we know? How do we know? Newton watched an apple go Falling down from way up high He asked the question — tell me WHY?

He did the math, he figured out The same pull — without a doubt — That pulls the apple from the tree Keeps the moon where it should be!

Gravity! Gravity! Pulling you and pulling me! Gravity! Gravity! Pulling everything we see!

Jump up high — you'll come back down Gravity won't let you leave the ground It holds the moon up in the sky It's the reason things don't fly!

How do we know? We dropped and checked We measured every single speck We tested it a thousand ways And gravity works every day!

Gravity! Gravity! Pulling you and pulling me! Gravity! Gravity! Pulling everything we see!
