  1. Basically when doing anything in life physics is involved. When driving physics is involved. Driving is all about getting from one place to another in the quickest amount of time because time is a precious thing and noone wants to waste it. When going from one place to another and then back to the same place from where you started is called displacement. When driving there is a certain speed that you are allowed to go. To get up to the speed that you want you must make you vehicle accelerate to the speed that you want. The velocity is how fast that your car is going. If you are stopped at a red light or a stop light your car won't go anywhere because according to Newtons first law an object at rest tends to stay at rest unless acted upon another force which could be you moving your foot from the break pedal to the gas pedal.
  2. I played soccer for 10 years. Now that I am in a physics class I am learning that there is physics in soccer all the time. The point of soccer is to put the ball in the opposing teams goal. The only way to do that is to kick or head the ball in. Kicking is the most important part while playing soccer because if you want to dominate the field you have to be able to control the ball and be able to move it around the other team by using your feet. When someone kicks the ball they are putting a force on the ball which is greater than the ball so the ball moves through the air. When someone puts a great force on the ball it goes through the air which is a projectile. The ball has an intial vertical and horizontal velocity the acceleration of the horizontal does not change but the acceleration of the vertical is always 9.81m/s^2. Depending on the force and angel at which the ball is kicked will effect what the velocity, speed and how far the ball goes.
  3. As most know i love to play sports. One of the sports that i play is lacrosse. While playing lacrosse there is physics happening all the time. Lacrosse can be related to Newtons first law. Newtons first law is that an object in motion tends to stay in motion unless acted upon by an unbalanced force. In lacrosse if someone throws the ball it is going to stay in the air and travel at the same speed unless someone puts their stick in the way to make it stop. Depending on how far away you are from the other person that you are passing to you have to put a certain amount of force behind it. If the person is close you only have to put a little force on it. If the person is far away then you have to put more force behind your throw.
  4. This past weekend I had to drive to Canada to play in a hockey tournament. While i was in Canada we had to drive on the expressway to get to the ice rink and as we were driving I saw a sign that reminded me of physics on the side of the road. The sign was a speed limit sigh and it said 70 km/hr. This reminded me of physics because for us Americans to know how fast to drive we had to do a metric coversion to get 70 km/hr to mph. After doing a metric conversion 70 km/hr turns into about 44 mph. You can learn how to do metric coversions by watching the metric conversions video on APlusPhysics.com.
  5. As young physicists, we determined the acceleration due to gravity by dropping a ball from an intial velocity of 0 m/s from a distance of 2.78 meters. We did multiple trials for trial 1 the time it took fort he ball to drop is .63 seconds, for trial 2 the time it took the ball to hit the ground was .60 seconds, and lastly for trial 3 the time it took was .65 seconds. To determine the accelration of each trial we used the formula d=(vi)(t) + (1/2) (a)(t)^2 , we then isolated a and got the answer of 14.00 m/s^2 for trial 1 and for trial 2 the acceleration was 15.4 m/s^2 and for trial 3 the acceleration was 13.2 m/s^2. This shows that acceleration can easily be found by using kinematic equations as long as you have 3 parts of it, you can solve for the other 2.
  6. This makes a lot of sense good job
  7. When playing ice hockey there is alot of physics. For example, when skating up and down the ice surface the average velocity that one person is creating increases as their speed increases. When ones stick come in contact with the puck the velocity can change. The displacement of the person changes as the movement of the puck changes because the person wants to stay in the play of the game.
  8. Hi Stephanie! Good for you playing in the travel softball league good luck in physics!!
  9. Hi reed! I can,t wait to start building things! I hope this year is fun maybe we can study together sometime

    About me

    I love to play sports. I play ice hockey, field hockey, and lacrosse. I am captain of my field hockey team. I have a very big family. I have four sisters katie who is a junior at Utica college and is a physical therapy major. Abby who is a freshman in college at MCC then there's me a senior in high school then the twins Emma and Rachel who are in 6th grade at Iroquois middle school. I like to hang out with family and friends when I get the chance. My intrests include playing sports. I love to be busy! I have a part time job at staples where I work when I can because I have a car and need to pay for gas money. In physics this year I hope to be able to learn about why things happen and how they happen. I hope that learning physics will be fun for me and not boring. I know that I will struggle but I hope that I can get past it. I am taking physics this year because in my future I plan to go to college to be an occupational therapist and I know that I need to take alot of sciences when I do get there and in taking this physics I hope that who I get to college and need to take physics again I will be able to know a few things instead of learning everything for the first time. I am excited to learn about physics and hope I do we'll this year. Thanks for reading!
