What Is Gravity?
Storyboard Text
- Hey Susan, why don't we float?
- Well Jonas, The reason that we don't float away is because there is an invisible force holding us down.
- I think I've heard of something like that before, is it gravity?
- Very good Jonas, it is called gravity. Do you know how it works?
- No not really, do you think you could explain it to me?
- Of course Jonas, gravity is a force of attraction that pulls together all matter. The more matter something has, the greater the force of its gravity. That means really big objects like planets and stars have a stronger gravitational pull.Do you understand that?
- That makes total sense, so is gravity the reason why planets stay in place?
- Exactly right, it is also the reason why objects fall to the ground, just like that coffee cup.
- Thanks for all your help Susan, I just have one more question, who discovered gravity?
- That's ok Jonas, and to answer your question Sir Isaac Newton discovered gravity.
- Thank you so much Susan, I now fully understand what gravity is!
- Thats alright Jonas, and if you have any more questions feel free to ask me.
