Newtons
Storyboard Text
- Hi Daniel! Today we learned in physics about Newton's Laws and I am just so confused. Can you explain to me the First Law?
- You know what how about I demonstrate you how the First Law works? Let's do this!
- Did you see that?! I just swung a bucket of water and it stayed perfectly put in its place.
- That's crazy cool! Is that because of inertia like the teacher explained? It makes sense because water in the bucket is in motion and it continued to remain in motion even if the bucket was going in crazy circles..
- Bucket filled with water swung in circles
- I'm pushing this cart. Look, when I add more groceries into the cart, I need to push it harder it to accelerate faster. But when there is less mass, less force is required to accelerate it.
- Cart with groceries
- I'm just going to sit here. Show me how Second Law works? Something to do with force, right?
- This has something to do with the Third Law, I'm pretty sure?
- Yep, so we are sitting right now on a staircase. We are still and not moving yes? Well, according to Newtons 3rd Law, for every action force which is us sitting, there is an equal and opposite reaction force. Let me explain more.
- Force: moon acting on earth = force: earth acting on moon
- Let's pretend we're in space. The force from moon acting on the earth is the equal and opposite from the force of earth acting on the moon. Do you understand now?
- Well, do the laws make more sense now to you?
- Oh yes definitely! Newton's laws are cool, I didn't know we use them so much in our lives. But, now I can be confident in class tomorrow. Thank you!
