ukerub technique - Unit 5

In class today, we went into depth about Newtons three laws of motion, free body diagrams, and vectors. My last blog post talks a lot about the definitions, but for this post i want to see how they apply to daily life. In class, Mr. Blake mentioned how when a car veers to the left, the people in the car actually lean to the right. This was something I had always learned about, and just now I realized that it's physics baby! This is my explanation of what goes on in the car when this "jello" game happens. Let's say when in the car, it is going a constant velocity, so therefore it isn't accelerating. However, when you turn your car to the left, you are accelerating because you are changing the direction (assuming that you are not changing the velocity when you turn, even though you should decelerate for safe driving). Because of Newtons first law of motion, we know that an object in motion will stay in motion unless acted upon by an outside, unbalanced force. So when driving in a car, your butt and feet move the same way the car moves because it is connected to the car, but your head and most of your body isn't, so inertia makes your body want to still move forward, when the car is moving left. Thus, you move in the opposite direction you are going to continue going where you were going before the car changed directions.

  1. Sandra, your blog is super pretty. It's so bright and happy and it makes wanna drink orange soda! I really like how you made such a tangible direct application from the concepts we've learned into our daily lives - very helpful. Awesome job!
