How do you calculate speed from force and horsepower?
Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.
How do you calculate energy from power?
Electrical energy is the product of power multiplied by the length of time it was consumed. So if we know how much power, in Watts is being consumed and the time, in seconds for which it is used, we can find the total energy used in watt-seconds. In other words, Energy = power x time and Power = voltage x current.
How do you calculate average power output?
Figuring out our average power output, we simply divide the energy by the number of seconds in a day, 86400, which gives a bit more than 100 W. In other words, on the average, we’re just a little brighter than your average light bulb.
What force is exerted by a motor that does 260 J of work moving a 2.2 kg object a distance of 4.5 m assume there is no friction?
What force is exerted by a motor that does 260 J of work moving a 2.2 kg object adistance of 4.5 m? Assume there is no friction. The object must acquire 260 J of kinetic energy. ½m*V² = 260 → V² = 2*260/2.2= 236.36 m²/s² a = V²/(2x) = 236.36/(2*4.5) = 26.26 m/s² F = m*a = 2.2*a = 57.78 N 2.
How fast is 7 hp in mph?
How much is 212cc in mph? This engine is a performer right out of the box, and should get your go kart running anywhere from 20 mph all the way up to 35mph in its stock form.
What is the force of 1 horsepower?
James Watt determined that one horse could exert 330 pounds of force in moving a load 100 feet in one minute. also be expressed as 1 hp = 33,000 foot-pounds/ minute or 1 hp = 550 foot-pounds/second.
How do you find work when given power and time?
Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.
How do you find energy with power and time?
Electrical Energy = Power x Time. The total amount of electrical energy used depends on the total power used by all your electrical devices and the total time they are used in your home. One kilowatt hour is equal to 1000 watts of power used for one hour of time.
What is the efficiency formula?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.
How do you calculate work output?
The formula calculating work output is F*D/T, where F is the force exerted, D is the distance and T is the time. The work output of a system is also described as its Power. In order for work to be done, force has to be applied in the direction of the motion. Using this, work is calculated as Force * Distance.
How do you calculate output?
Total output can be measured two ways: as the sum of the values of final goods and services produced and as the sum of values added at each stage of production. GDP plus net income received from other countries equals GNP. GNP is the measure of output typically used to compare incomes generated by different economies.
What is power output measured in?
Electricity is measured in units of power called Watts, named to honor James Watt, the inventor of the steam engine. A Watt is the unit of electrical power equal to one ampere under the pressure of one volt. One Watt is a small amount of power.
How do you calculate force normal?
The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Multiply the two values together. In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.
How much does the gravitational potential energy of a 1.2 kg textbook increase if you lift it upward 32 cm?
How much does the gravitational potential energy of a 1.2 kg textbook increase if you lift it upward 32 cm? PE = mgh 32 cm =0.32 m, g = 9.8 m/s2 27.
How high up is a 3.00 kg object that has 300 J of energy?
Answer: The height of the object is 10.204 meters.
