This video explain why light slows down when it travels through glass and water, and it speeds up when it comes out.
In this image the cyclist was rushing to get the red light. It is physics because the cyclist was accelerating. The motion of the cyclist will be ■ ■ ■ ■ ■ ■
Also, an increasing distance between the images shows that the object is speeding up.
This photograph is showing a thousand of car on a bridge.It is 5 PM, people are getting out or going to work, therefore ecause is traffic all the cats are at rest. Also, it is important because the construction of a bridge requires cateful planing. And in order for engineers, or architects to build bridges, they need to apply the basic concept of physics such as graph, mass, and a detailed drawing.
This image is showing a couple of birds flying. This example also demostrates the speed of air relative to the ground. We should also be aware and know that the wind could make the birds move faster relative to the ground, or could make them move in the wrong direction.
Researchers have shown that birds can not fly in the moon. Therefore, if there are no air resistance birds can not fly.
While waiting for the train this morning I had an intriguingly beautiful view of the sun rising. So, I decided to take a picture; it just so happens that I caught the train in the picture as well. Just like in the previous post regarding the helicopter, the train exemplifies constant acceleration as well as constant and changing velocities. I'm started to see things in relation to the concepts we have learned in class and from the textbook (physics is everywhere!).

I woke up to the sound of police sirens one morning. When I looked through the window to check it out I saw police cars and helicopters (someone's in trouble). The helicopter is an example of a few concepts we have explored so far such as velocity, displacement in relation to time, and acceleration. There are also two different forces acting on the helicopter (air resistance and gravity).

On my way home, my family and I were stuck in traffic for an increasingly long time (time frustrates my father .. he's impatient). The cause of the traffic was a car accident; thankfully no one was seriously injured. However, it reminded of Newton's third law which states that for every action there is an equal and opposite reaction. In the picture you see the front of the car impacted the barrier. The reason that there is a good amount of damage to the car is because the force of the car when it comes into contact with the barrier is the same amount of force the barrier is exerting back towards the car and the barrier does not budge from its position.

Hey guys,This is another helpful video I found. This one is about free fall. This video offers you a visual outlook of free fall, as well as the equations and math required to solve the equation. Like most of you guys know I learn from equations and looking at things from a mathematical and visual outlook so these videos are really helpful to me.
Hope you enjoy them,Amelia Tavarez
Hey guys I know were all studying for this midterm and as I was studying I decided to look up so videos on concepts we have learned that will help me study. Here is a video on projectile motion, videos like this are fun, keep you involved but also teach you. Hope you enjoy the video and clarify some of the confusions you have.

This photograph was taken when I was waiting for the light. And it is showing the black car, a mercedes I believe, moving at a constant speed at first, but slow down in order to make a turn. There for the motion of the car moving at a constant speed will look like this ● ● ● ● and the motion slowing down like ■ ■ ■ ■ ■ ■ ■■

This is an example of projectile motion, something we worked on lab# 6. Thanks to lab #6, now I know that LeBron's horizontal velocity is constant throughout his jump, something I would have never thought because visually to us he appears to be moving faster & faster horizontally, but in reality he's not, his horizontal velocity is constant. CRAZY!

http://www.youtube.com/watch?v=X8GFWVy2ghM, If you fast foward to about 24 seconds into the video to the cat jumping up and off the chair, you will see physics. When I first saw the video I was let down, such a long video and the cat doesnt even jump that high. However, when I was working on my lab write up for projectile motion all I could think about was physics. Just from this video we can see it took the cat less than 5 seconds to jump off the chair and free fall down to the floor (Note that he hits almost hits himself with the table). We can analyze both his horizontal motion a vertical motion independently. This makes me wish we had cats in our classroom that would help us as stunt doubles in our videos. It would be a little more exciting than dropping a ball. Do you think?

Hello all,
Since we are starting to learn about free fall I thought it would be useful to share a link to a video on free fall. It is a song, a bit nerdy, but nevertheless helpful because it explains the basics of free fall.

Every single one of us in the classroom at some point has or will use the electric stairs inside John Jay College. Now that I am taking physics and learning new concepts I have realized the electric stairs travel at a constant speed because all parts of the stairs move simultaneously. However, many would say the electric stairs move at a constant velocity, but in reality this is not true. Even though the speed remains the same, the direction of the electric stairs changes, therefor it is incorrect to say it has a constant velocity because there is a change in direction.
