Therefore, the car developed an average of 78.0 horsepower, not 100 horsepower. Is force work divided by distance? A: A force is described as any influence that causes an object to undergo a change. You cannot use force and distance alone, however; since kinetic energy relies on mass, you must determine the mass of the moving object as well. You know that F = ma, so you can plug in the values to get. Now all you need is the average speed. A Force divided by Distance: looking at the units, Force = newtons = kg m / s^2 = mass x length / time^2 so You know you can also calculate average power as work divided by time: And the work done by the car is the difference in the beginning and ending kinetic energies: The car started at rest, so KEi = 0 J. However, because you often have to account for acceleration when you apply a force, you usually write the equation in terms of average power and average speed:
\n\nHeres an example. Unbalanced forces are forces that cause a change in the motion of an object. On the big Physics Test Track on the edge of town, you measure its acceleration as 4.60 meters/second2 over 5.00 seconds when the car started from rest. However, the objects speed, v, is just s divided by t, so the equation breaks down to
\n\nThats an interesting result power equals force times speed? Electrostatic force (F) is inversely proportional to the inverse square of distance. The distance formula in coordinate geometry is used to calculate the distance between two given points. You can use a dash (-), period (.) t = 10.0 min. equal to work, which is basically a transfer of mechanical (1) When distance between objects is doubled, force of attraction will become 122=14 times i.e. distance divided by time. by 1 square meter. The force you feel is the weight of the water above you. The change in pressure could also cause the nitrogen in your blood to form bubbles and give you the bends! 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. In a mechanical problem, power is the time derivative of energy or work. There is an electric force expression. Solve this formula for - Brainly.com codyminer22 06/24/2019 Mathematics Middle School answered expert verified The formula W = Fd shows the relationship between work, force, and distance. However, because you often have to account for acceleration when you apply a force, you usually write the equation in terms of average power and average speed: Heres an example. Thus 1 N = 1 k g m s 2 Force = mass times length divided by seconds squared. Recall what the force exerted per coulomb of unit +ve charge placed at a point represents.. What is force times time? That means that 14.7 pounds of force are pressing in on every square inch of your body at sea level. RANK. ANSWER. 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? He has authored Dummies titles including Physics For Dummies and Physics Essentials For Dummies. Dr. Holzner received his PhD at Cornell.
