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\r\n\r\n\r\n\r\nWhat force does the water exert on the back of your hand? One horsepower = 745.7 watts, so, Therefore, the car developed an average of 78.0 horsepower, not 100 horsepower. Let's substitute our values nine times 10 to the nine for our K times 1.6 times 10 to the negative 19 for the Q. Work is a measure of the energy expended in applying a force to move an object. Average speed is the total distance traveled divided by the elapsed time. What is distance formula and example? Air exerts pressure, too, due to the weight of the air above you. Distance refers to how far an object travels over a period of time. He has authored Dummies titles including *Physics For Dummies* and *Physics Essentials For Dummies.* Dr. Holzner received his PhD at Cornell.

Okay, so you agree to calculate power another way. The applied force can be both a contact force or a non-contact force. ","noIndex":0,"noFollow":0},"content":"Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, *P* = *F/A*. SURVEY . Air exerts pressure, too, due to the weight of the air above you. Force implies mass times acceleration, i.e., f = ma. I remembered when I first learnt the inverse square law, I was convinced that the inverse square law came from the density of the field line on a surface. The back of your hand has an area of about\r\n\r\n\r\n\r\nYou reason that if *P* = *F/A, *then the following is true:\r\n\r\n*F = PA*\r\n\r\nPlugging in the numbers and solving gives you the answer:\r\n\r\n\r\n\r\nYikes. Nowadays, springs are used in almost every industry. Time Entry Formats hh:mm:ss. Weigh the object on the mass balance. 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. The force for a given charge will be constant anywhere in this field. For times that are protons. Dummies helps everyone be more knowledgeable and confident in applying what they know. Heres a pressure example problem using water pressure. You can use the equation, You still need to convert to horsepower. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m^{2}. A thousand newtons! For the one with Force vs charge. 7. When you perform work, it generates kinetic energy. Then, the dimension of Force is Mass, Time, Distance per Time. The electrostatic force is equal to K. Cuban Q two divided by the square. So force is just the energy involved in moving an object divided by the distance the object was moved. Moment of force = Force x perpendicular distance from the given point to the line of action of the force Moment of force = F x l Torque It is simply the product of the force acting on the body and the perpendicular distance from the given point to the line of action of the force. It has a magnitude as well as a direction.. 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:

where *s* is the distance traveled. Power. One horsepower = 745.7 watts, so

Therefore, the car developed an average of 78.0 horsepower, not 100 horsepower.
