Fun+Slides

For this fun lab for the fun slides we used the theory of conservation of energy. At the top of the slide the rider would have potential energy, and kenetic energy at the bottom of the slide. It is a simple concept of physics. Potential energy is mgh. Where m is the mass of the object, h is the height at which it starts, and g is the force of gravity which is a constant of 9.8 m/s^2. Kenetic energy is 1/2m(v)^2. Where m is the mass of the object and v is the velocity of the rider. Conservation of energy uses the principle of that you have the same amount of energy at the top of the slide as at the bottom of the slide. So it can be siad that PE=KE. By using this equation, we were able to find the speed at the bottom of the slide and the potenial energy at the top of the slide. Also, we were able to find the mew of friction by using the conservation of energy. By using this equation 1/2m(v)^2=u(mew)gh. Where the constants are the same. We also tested how weight affected the speed of the ride by Hannah and I ( John) racing down the slide. I won every time becuase i had the greater potential energy at the top of the slide meaning that I had the greater kenetic energy at the bottom of the slide. Some errors that could have occured durring the lab could have been the wind, which could have slowed us down, measuring the slide, and pushing off at the top of the slide. Mass of John - 160 lbs --&gt; 72.575 kg Energy Potential Energy m*g*y 72.575kg*32ft/s^2*32ft = 74320 J Conservation of Momentum - Solving for velocity m*g*y = 1/2*m*v^2 g*y = 1/2*v^2 32*32 = 1/2*v^2, solve for v v = 45.25 ft/s
