Lacrosse Game

## physics at work

Working at the blue cross arena I get to witness many events that all include physics. One of the most obvious ones is hockey. The ice is a surface with very little friction. If you are wearing shoes with little traction it is easy to slide on the ice because of the lack of friction. What this does is allow for the hockey puck to glide across the ice and it will virtually never stop. There is some friction because it is not a completely frictionless surface but the puck would keep going until so

## Catapults

The catapult project that we just finished was not what I expected. When it was assigned I expected it to be very stressful and take a long time. With all of the materials already available it turned out to be not that bad even though our catapult didn't go very far. It also taught me more about physics and clarify things I wasn't understand. When we had to solve the questions after it was fun to figure out how well our catapult did. I wish that I was more involved with the building of the catap

## the physics of doing hair

Being a girl a generally spend some time getting ready for various events. Getting ready requires many different tools such as curling irons, flat irons, and hair dryers. These tools require a good amount of electricity to power and when you plug more then one of them into the plug the lights dim significantly. This is because the circuits that these are plugged into are only series circuits. This means there is only one path for the current to flow through and when you plug in another tool it r

## physics in disney

When I was in Disney with my bff Grace we saw that many of the rides contained different aspects of physics. One of these rides was called rockin n roller coaster. It is a roller coasted that launches you from 0 to 60 in 2 seconds. It does this by using large magnets that allow the coaster to accelerate faster and stop faster. The opposite charges of the magnets help slow the coaster and as it is coming to a stop the size of the magnets increase because that means a strong pull between the oppos

## work

Over the summer I worked as a cotton candy vender. What that involves is walking up and down the steps at frontier field holding a rack of 40 cotton candies above my head. This can represent newton's 3rd law because to keep my arm up I have to match the force that the cotton candy rack is pushing down on me. By the end of the night my arm would be sore because to match the weight pushing down I had to exhibit the same amount of force in order to keep it up.

## Lacrosse Problems

Every Sunday during the off season my lacrosse team plays in an indoor league held at mcc. During a game I got the ball and was running it down the field to score. The closer I got to the goal the more I started to accelerate when out of no where came a girl much bigger then me. Even though I was accelerating she had much more mass, so at the point of collision I ended up falling. She got kicked out of the game and I remained on the ground.

## physics football

With the super bowl coming up next month I figured I would talk about how power relates to O and D linemen. Power is equal to force â€¢ velocity. Offensive linemen and defensive linemen tend to have a large mass and are able to apply a lot of force in a small period of time. Since the linemen are able to apply such a large amount of force they cause a displacement in a short period of time. This means they have a lot of power which could be found using the equation.

## Work

Tug of war is a primary example of work in physics. Work is equal to force â€¢ displacement, in tug of war when each side is pulling back they tend to move from their originally spot so there is a displacement. Also if one person weights 60 kg and the other 80 kg, if the 80 kg person let go of the rope the 60 kg person would fly back father then if they were to let go because the 80 kg person had a larger mass meaning they probably had more force to begin with.

## Friday Night Lights

At the sectionals game on Friday against east ridge my boyfriend caught an interception. When the ball is thrown it is considered a projectile. The entire time the ball was in the air it accelerated at 9.81 m/s squared in the downward direction. The projectile also known as the football in this case makes the shape of a parabola going up and then down in a curved shape.
