Here we go: So this is a picture of my mom sliding down a hill on a snow tube. During spring break my family went on a trip to the Pacific Northwest. This was taken at the Cypress ski resort in Vancouver, Canada. Snow tubing is similar to sledding; all you do is slide down a hill. You can't really do tricks or anything, but you go pretty fast. At this moment, I am probably engaged in an extremely intense snowball fight with my sister (I'm winning of course). Any way, time for business. In order to generate any speed, you must first climb to the top or use the lift. When you slide down the hill, you end up back where you started from (the bottom). Thus, your total displacement is zero. Also, when you slide down the hill, you are displaying negative acceleration. This is a prime example of a person moving at a very high speed, but having negative acceleration. Even though my mom is actually gaining speed, her acceleration is negative because she is moving in the opposite direction.

that looks like fun jonny boy..also looks cold..next time i go sliding down a snowy hill, or the first time actually, i'll remember i have zero displacement
you cheater, half of that isn't even about physics
hey jon i like your joournal it just screams physic ! its like physics is everywhere.
that looks super fun. never got to slide down a hill before and realized it had to do with physics. haha and no auntie wendy didn't go on the roller coaster. just my sister and me. she went on the one at california adventure when we went with auntie danielle and nick couple summers ago though.
very cool...i love the snow! and i saw that youtube of the phonebooks.PHYSICS!!
