## physics in riding a dolphin

One of my dreams in life is to ride a dolphin at somewhere like seaworld or somewhere in Florida. But, how much power does a dolphin have? Power is really easy to calculate. But first you need to calculate the work done by the dolphin using the equation W=Fd. The force would be the weight of the dolphin multiplied by gravity (9.81m/s^2) and the distance would be exactly that, how far the dolphin would be swimming. Once you have calculated that, you can use the in the power equation which is P=W/

## physics in shopping

When there's a good sale going on, you need to move fast. How fast you ask? Well that would be easy to find out. You would need to know a few things before you could find out your acceleration though. If you rearrange the equation: Vf=Vi+at to A=Vf-Vi/t you could calculate the acceleration. You would need to know your final velocity and your initial velocity. Then, you would also have to know the time it took for you to get from your initial point, to your final point. When plugging all of those

## physics in the xgames

There is a lot of physics in the xgames. In my favorite event, the freestyle snowmobiling has a lot of physics involved. When a snowmobiler is doing a flip in the air, have you ever wondered how fast they're going? Well, you can calculate their centripetal acceleration. Using the equation Ac= v^2/r. First you need to find out the radius of the spin. That would be hard to calculate an exact radius, but you can find an approximate radius probably using the a meter stick. Then to find a velocity it

## physics in skiing

Skiing has a lot of physics involved in it. For example, the approximate coefficient of friction for waxed skis on snow is on the front of the reference table. Using the equation Ff=(coefficient of friction)Fn Using this equation, you can find the force of friction. All you need to know is the normal force and the coefficient of friction which is on the front of your reference table. To calculate the normal force you need to multiply the mass of the skier by gravity (9.81m/s^2). After calculatin

## physics in getting out of bed in the morning

As you may know, getting out of bed in the morning is a lot of work, especially if you're not a morning person. How much work you ask? Well lets calculate it. The equation for work is W=Fd. So if you calculate your weight and multiply that by gravity, 9.81m/s^2, you'll get your force in newtons. After that, you need to find out your distance/displacement. You could measure the distance from your bed to next to your bed or from your bed to the point that you first go when you wake up in the morni

## physics of my cat

Physics connects to everything in life, meaning physics connects to me playing with my cat Molly with a laser. When Molly isn't playing, she is at rest, but when the laser is being used she goes from rest to an increased acceleration. If I measured the distance she traveled, and the time it took, I could easily find out her average acceleration. Molly is a young and playful cat so I'm sure she would have a high acceleration.
