You think its kind of small, but he claims it has over 100 horsepower. Then, the dimension of Force is Mass, Time, Distance per Time. Solve this formula for distance. You can use the equation, You still need to convert to horsepower. distance divided by time. QUIZ . Then for the charge graph, I'm not sure what the units of charge even are. What is force times time? Youre near the deep end of the pool, and using the handy pressure gauge you always carry, you measure the pressure on the back of your hand as, What force does the water exert on the back of your hand? For example, the previous equation becomes: Divide the left side of the equation by the number on the right side of the equation to isolate v2. How much horsepower is that?
\nYou know that
\n\nso all you need to calculate is the average speed and the net applied force. In addition, there are many spring designs, shapes, and sizes available. Simply put, it is the gradient of the force versus deflection curve. a. force onan object divided by the time the force acts b. work done times the time taken to do that work c. work done on an object divided by the time taken to do that work d. distance divided by the time taken to move that distance c. work done on an object divided by the time taken to do the work the unit of power is the a. newton b. meter C When a force acts on a body that is free to move, the force is the work done by the force divided by the distance moved by the body. The air pressure at sea level is a standard pressure that people refer to as 1 atmosphere (abbreviated atm): If you convert an atmosphere to pounds per square inch, its about 14.7 psi. One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m. Work can be calculated with the equation: Work = Force Distance. (Average speed is not the magnitude of the average velocity.) Okay, you say, getting out your clipboard. in this case, "distance" means how far the spring has been moved I demand a recount.
\nOkay, so you agree to calculate power another way. Is force equal to energy? That leaves only the final kinetic energy to calculate:
\n\nPlugging in the numbers gives you:
\n\nSo because
\n\nand the work done was
\n\nyou get the following:
\n\nAnd, as before
\n\nDouble rats, your brother says.
","description":"In physics, you can calculate power based on force and speed. If you have a 700 g object, for example, divide by 1,000 to get 0.7 kg. Rats, says your brother. Assume friction is negligible in your calculations, so that the work done on the object equals its kinetic energy. This explains why force remains constant, as electric field strength is voltage divided by distance. The mass and velocity of an object impact how much kinetic energy it has. E.9 The work required to compress a spring through a displacement of meters, starting from rest, is then (E.6) Work can also be negative. 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Power, with units of watts, is the rate at which work is performed or energy is expended. The electron can be divided by the distance. Work is equal to Force multiplied by distance. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel:
\n\nwhere s is the distance traveled. Say the starting speed was vi and the ending speed vf . He has authored Dummies titles including Physics For Dummies and Physics Essentials For Dummies. Dr. Holzner received his PhD at Cornell.
