Forms of Energy

Energy is described as the capability to accomplish a task, like the ability to push a block by applying force on it. It is a quantitative property that is used to accomplish work on an object.

Are you as strong as a horse?
Purpose: To understand the concept of work and power and to calculate the power
generated by yourself or a friend.
Materials: A tape measure, stairs, and a stopwatch, cell phone, or wristwatch.
Key Physics Concept: Power is the rate of doing work. Power can be calculated by
dividing the work done by the time it takes to do the work; in this case we will do work
against gravity on a stair case (you may add your power in doing pushups to test your
arm power). Can you guess what your peak horsepower is?
You may do the stairs one at
at time or multiple stairs at a
a time; whatever is most safe
and efficient for you.
Procedure:
Observations:
Analysis:
Conclusions:
Application:
1. Will your hp change if you performed the activity for a longer duration (for example,
climbed the CN tower staircase)? In what way? Explain.
2. Research the horsepower generated by a car. How does the average person's peak
power rating compare to it? How many average people would it take to generate the
same horsepower as the typical car?

A student struggled with his first midterm exam and is slightly angry. For this reason he drops a 10 kg object on the good teacher from a height of 5 m. When seeing the object fall to the ground, the teacher asks the logical question: How much will the internal energy of the box have increased after hitting the ground? If the specific heat of the box is cp = 3 kJ / kg.K How much will the temperature of the box have increased?

1. Is it Worth IT? I am considering purchasing a cover for my swimming pool. I have estimated that my pool loses 1.5 in of water off of its 1200 ft² surface each week due to evaporation. The cost of energy to heat the pool averages about $10.00 per million Btu. Interestingly, the salesperson at the pool store claims that a $500 pool cover will reduce evaporative losses by two-thirds and, as such, will pay for itself in one 15-week swimming season. Is it worth it for me to purchase this pool cover? You can assume that the heat of vaporization for water at my pool's average temperature equals 1050 Btu/lb.
2. The goal of this problem is to select a power plant and battery for an electrically powered light sport aircraft with the following specifications: • Total mass 500 kg • Cruise speed 50 m/s • Takeoff speed 30 m/s • Lift:drag ratio 10 Max climb rate 5 m/s Range 500 km Reserve: 30 mins in level cruise (you can take the gravitational acceleration g=10 to keep the arithmetic simple) Using the information provided, please calculate: 2.1 The magnitude of the drag force acting on the aircraft during level flight at cruise speed 2.2 The engine power required for level flight at cruise speed 2.3 The battery capacity required to achieve the necessary range, plus 30 mins reserve (at cruise speed). Please give your answer in kWhr (kilowatt-hours) 2.4 The engine power required to achieve the necessary climb rate (assume the same drag as in level cruise) 2.5 Assume that the magnitude of the drag force on the aircraft, F, is proportional to the square of its speed V, i.e. F, =cV² where c is a…
4. An electric motor is used to drive the shaft of a small water pump. During a performance test, the torque on the motor shaft is found to be 8.23Nm when the motor is drawing 716 W of electrical power. What is the rpm of the pump shaft if it has an efficiency of 76%?
A resistor is wired to a battery in a circuit and dissipates a power P1 as heat. A second battery, with the same voltage, is added in series with the first battery, leading the resistor to dissipate a power P2 as heat. How much does the resistor dissipate with two batteries, relative to with one battery, or in other words, what is the ratio P2/P1?
2. Some of the first power-generating wind turbines were small, having blades with a radius of 8.00 meters. Currently, the largest wind turbine has a radius of 164 meters. Because the small wind turbines are closer to the ground, they often experience smaller wind speeds. Given the information below, how many small wind turbines would be needed to produce the same power output as one large wind turbine? For both wind turbines, assume the air density is 1.23 kg m³. Small Wind Turbine Large Wind Turbine Wind turbine blade radius 8.00 m 164 m Wind turbine efficiency 35% 45% Wind speed 3.50 m s1 5.50 m s1
