Watch out.

This week was an insightful week of momentum. Momentum is very similar to  inertia, which is a moving quantity that has direction and magnitude. Momentum can be calculated by multiplying an objects mass (kg) by its velocity (m/s). Boxing can be relative to this because change in momentum is equal to the force times time. So if you punch with a larger forcer it will hit the face faster but if you the force is smaller it will take longer. Despite these opposite ideas they will still have the same momentum.  Isnt that mind boggling?

Let it Fall

We were able to learn about Newton's first law on how an object in motion will stay in motion unless acted upon by an outside unbalanced force and an object at rest will stay at rest or better known as the Law of Inertia. Inertia is an object's capability to stay in the same state of motion. An object's inertia is directly proportional to an object's mass. A great example of this is the waterfall I visited this weekend. The water wants to continually flow and fall. However once it reaches the bottom it can no longer fall. But even after the water falls it wants to continue to move which is why it flows down the river.

Make a Wish

I know Im not the only one who likes to throw coins into the koi fish pond at ala moana. Walking around the mall gets tiring and as I was sitting on the bench of the second floor shops when I see this little boy make a wish and throw his coin into the pond below. Seeing this I thought of projectile motions. If I wanted to find the height at which the second floor from which he was throwing it at of I would need to know the angle in which he throws it and it's velocity. With this information I can plug and chug into a combination of trigonometric, acceleration, and distance equations.

How does this relate to me?

I got to enjoy a luxurious weekend on Big Island and here I still had to think about my science homework. One of things that I relished watching my dad surf and stand up paddling in the river

. Now you're going to wonder about how the hell does this relate to physics. You have to think broader, this involves MOTION. But all motion is relative depending upon the perspective you see it from. In this scenario, I would say I'm a pretty good surfer because RELATIVE to the surfboard I didnt even budge. I was able to stand up the entire time. However relative to the ocean I was constantly moving, not a moment I was still. Just to confuse you I was moving and not moving at the SAME TIME. muahaha!
