I am More Powerful Than a Ford Mustang! Concepts Energy, Work, Power Introduction Ever wonder if you can be more powerful that a Ford Mustang? Now is your opportunity to find out! The concept of horsepower (the English unit for power) tells you how much energy a car generate in a given time period. In this Lab, you will learn how to measure horsepower and how to relate it to an everyday object--yourself. So get your running shoes on! You will have your chance to show up a Mustang. By the way, the 2002 Ford Mustang Coupe GT has 260 horsepower. Procedure • Start by sending your partner to the very top of the stairwell in Parker Hall (3 R). • Have the same partner give you a ‘marks, get set, go!’ • Run the stairs as fast as you can to the top of the stairwell and meet your partner, who will be timing your run with a stopwatch. • Record the time. • Weigh yourself. • Determine the distance between the 1st floor and the 3rd floor. • Record your results and answer the lab questions about the power you expended. 26 Part B: Soap Box Derby Concepts Conservation of Energy; Work Done by Friction; Transfer of Energy Introduction You’ve learned that energy is always conserved. Energy only changes form and never just disappears. In this Lab, you will get to witness this phenomenon first hand. An easy way to do this is to simply drop something or let it slide down an inclined plane and witness the potential energy transfer to kinetic energy. Procedure Part 1 • Weigh the car to find the mass. • Incline the track by using the stand at one end of the track. • Measure the height of the track. • Determine the potential energy that the car will have at the top of the track. (remember to subtract the initial height fro the final height). • Put the car at the top and release it. • Record its velocity at the bottom of the track. • Find and record it’s kinetic energy at the bottom of the track.
