One of my favorite places in the whole world is Disney World. Like it or not-- Physics is everywhere in the Disney parks. Disney Imagineers always think of new rides and how they can work safety. A great example of the use of physics is on the ride, The Rocking Rollercoaster in Disney's Hollywood Studios! The Rocking Rollercoaster goes from 0mph to 57mph in the short time of 2.8s. When designing this coaster, imagineers must of utilized kinematic equations in order to determine the initial velocity, the final velocity, the acceleration and the time in order to insure safety. Another ride that utilizes physics in it's design is the Tower of Terror. The Tower stands at 199ft tall and as you move in the ride, it takes you up like an elevator and then rapidly drops you in 1.5 seconds. What is interesting about this ride is that it has a faster acceleration than the speed of gravity, meaning it goes faster than 9.8m/s (according to the Disney website) which is why when it drops you rise out of your seat a little and have to be strapped in very tightly.

Physics largely impacts driving. Newton's Laws of Motion can be used to explain this further. Newton's First Law states that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by a net force. This connects to driving because it explains why you must apply a force to brake and why when you crash you stop because some other force like another car has acted upon you. Additionally, cars have mass which means that cars have inertia. The first law can also be used to explain the need for seatbelts in cars because when we are in cars we are traveling along with it. As a result, we must wear seatbelts to hold us back if we suddenly come to a stop. Newton's 3rd law also can be applied to driving because it states that forces come in pairs. This principal explains why when 2 cars get into a crash both cars exert some sort of force back on each other.

Physics is a big part of dancing. For example, when a dancer leaps or jumps, gravity pulls them down and when a dancer is suspended in air, the only force acting upon them is gravity. When a dancer is doing a combination across the floor, they are going to a certain direction and typically moving at a constant speed. Velocity also contributes to dance because when a dancer turns, the faster they go the more turns one can do and it improves their skill. When a dancer is at the barre and they releve or are in pointe shoes, they are pushing against the floor which means that the force of gravity is equal to the force into the floor, which allows a dancer to balance.

My calculator makes me look like a smarTI

Hi Issac! I took physics because it seemed unique to other sciences too!

Kyra! You do such interesting stuff! I like how you explained how to say your name! I'm also excited for physics!

My name is Lia and this post is a bit about me. I am currently a junior and I'm excited for the new school year. My favorite school subjects are English and Social Studies, but I also enjoy science. In addition to school, I have participated in musicals since a young age and am active in voice lessons and dance. Also, I love to travel, watch movies and I am always willing to try new things I decided to take Physics this year for a few reasons. Firstly, I heard physics is a fun class that is rewarding and challenging. Also, I wanted to take another regents class. Additionally, I want to see which science I like the most so I can take an AP science my senior year. This year in physics, I hope to gain the basic knowledge of the science and see connections to physics in everyday life. I am excited to begin learning physics.
