In physics we're starting to learn about projectile motion. Projectile motion is parabolic due to the force of gravity. At first, I had the hardest time thinking of where to find an example of a parabola, when in reality, parabolas are everywhere! I found the perfect example of a parabola at my own house. This is a picture of the water fountain in front of my house, which forms a parabola when you turn it on. If there wasn't such thing as gravity, the water would've continued to rise higher and higher and never come back down. Luckily, it did, and I got to drink some water. If I were to place a hose at the exact same height as the water fountain, facing downward, both the fountain and the hose water would reach the ground at the same time. This is because gravity only affects vertical velocity, not horizontal, so the water is accelerating towards the ground at the same rate.
lol im glad gravity let u drink the water :P
ReplyDeletevery cool how u applied physics to something as common as drinking water!
I like your picture Sarah! It really shows how you can fing physics everywhere!
ReplyDeleteThis picture is very artsy. I like how it shows the path of the projectile throughout. Great job and great blog!
ReplyDeleteI love your picture! And really creative blog about daily physics!
