Physics in Softball

## Physics of softball

So everytime I need to make blog posts I always try to connect what we have been learning in physics to my favorite sport: softball. Now you might think that there are no waves in softball but I am creative and I believe I have found some sort of wave while playing softball. When people throw a softball really high it creates a giant lob that looks like a parabola. And this lob could also look like a half a wave. And if you measured from the ground to where the highest part of the ball reached,

## Wave games

When I was little we would always play this game with the jump rope we would call "snake". Two people would hold either end and kneel at the ground and wiggle the rope parallel to the ground causing waves to be going back and forth on the ground. And the object of the game is to jump over the jump rope without the "snake" getting you. First you would start off small, with little amplitudes. An amplitude is measured from the baseline to the top or bottom of the wave. And as the game progresses th

## What I learned in physics

A very important equation that we have learned is V=fh. The V is the velocity. The f is the frequency. And the h (which looks like a fancy backward h) is te wave length this is called lamda. The velocity of air in STP is 331m/s. How we applied this equation is questions would be asking you to find something in the equation. So for example if you were asked to find lamda given the velocity, you would plug in what you have and solve. Like if the wave was traveling at a speed of 10m/s and the frequ

## Physics on beach

I am going to myrtle beach for spring vacation!! So I figured I would talk about the waves I will see on the beach. The waves at the beach are transverse because they move up and down. As the water moves to shore the waves move up and down. People can cause a disturbance in the water distrupting the waves path. The best waves to surf are ones with really high amplitudes. When the ocean is angry the amplitudes are even higher! I can't wait to go observe the waves on my vacation.

## What I learned in physics

We have been learning about waves. A disturbance is called a pulse. To measure amplitude you measure from baseline to crest or from baseline to trough. Transverse waves can only move up and down. Longitudinal waves move parallel to the wave. Sound waves require a medium. Sound waves are longitudinal. Mechanical waves also require a medium. That's it folks. Peace.

## Physics of curling

As we all know the Winter Olympics are rapidly approaching, so I would like to do my entry about the physics of curling. Awhile back we learned about friction is the resistance that one surface or object encounters when moving over another. And as I understand the object of curling is to get your stone to the center, and knocking other people stones out of the way. There are also sweepers that go in front of the stone to smooth the ice to make the stone go faster. This involves friction. The mor

## Physics in working out

Last unit we learned about work, energy and power. And I noticed something when I went to the gym. I was on a cardio machine and i saw that it was telling me how many watts I was producing. I remembered in class that we learned about watts. They are the units of power, joules over time. So I guess that while I was working out, it measured how much power I had. And when I started to to faster the watts went up. I was producing more energy in the same about of time which will increase the watts as

## What I am Learning in Physics:

Right now we are in the unit of work and power. Work is the process of moving an object by applying a force. And for a force to have done work on an object it must have caused a displacement. And also the force and displacement must be in the same direction. The formula is W=Fd. The W standing for worl. The F as the force. And the d standing for the displacement. And the units for work is joules. Power is the rate at which work is done. The same amount of work can be done with different supplie

## Physics of Skiing

Now that the winter has arrived, ski season begins. And physics is involed everywhere in physics. Especially with our current unit about power and work. Work is the process of moving an object by applying a force. Power is the rate at which work is done. When skiing, the ski lift does work on you. Everytime you go up the ski lift, it is lifting you and your mass up the mountain. Also when people get hurt, the ski patrol does work on you. Because when you are in the little sled that carries you d

## Physics and Softball

Last unit we learned about circular motion. And circular motion can be applied in many places while playing softball. One instance in particular is when you are pitching. I am a pitcher and circular motion is involved alot considering your arm is traveling around in a circle. If you were allowed to have you arm travel around more than once you would be able to find your arms centripetal acceleration by using this equation: A=v^2/r. You could also find the frequency aka the number of revolutions

## What I Learned in Physics...

The unit that we are going right not is impluse and momemtum. I have learned many new things about these topics. For example, the definition of momentum is how hard it is to stop a moving object. And the definition of impulse is the change in momentum. We also learned many equations for this unit. Like, p=mv which will help you find momentum. Also J=Fnett=change in momentum=mdeltav. All these equations can help find impulse. And it is easy because everything equals everything. Lastly i learned t

## Physics of Calc

You may not know, but there can be a lot of physics involved in doing calculus. For instance after doing homework for several hours at night and you discover that you have been doing it all wrong, you might feel the need to crumple up you wrong work and throw it across the room. Doing this can I involve physics. When you launch the paper it would be at a certain degree. Knowing the ideal angle is 45 degrees you would get as close as you can to that angle to launch you homework as far as you can.

## Physics of Softball Again

So I've already done softball in physics before, but now that we have learned new material I thought I could show more physics that applies to softball. Projectile motion is everywhere in softball. When you throw a ball the ball will almost always make a parabola. Which is the shape of the projectiles we have been looking at in class. Also you can use projectiles when trying to see which ball will go the farthest at the same velocity. If the ball goes higher it won't go as far as a ball that's t

## Physics in Softball

In softball, physics is applied throughout the sport. For example, when you run from home to first base, you start at a velocity of 0m/s and it increases as you run. Also when you round the bases when getting a double or triple, your velocity decreases as you approach the base and then it increaes and slows down again as you run around the bases. Also when you are hitting the the pitcher throws the ball and when you hit it the velocity with be 0m/a until the ball bounces and it's velocity increa
