7. The force is along the straight line joining the two charges. Force implies mass times acceleration, i.e., f = ma. The spring rate of a spring is the change in the force applied divided by the change in diversion of the spring.

Dr. Steven Holzner has written more than 40 books about physics and programming. The change in pressure could also cause the nitrogen in your blood to form bubbles and give you the bends! 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\n

Heres an example. A: A force is described as any influence that causes an object to undergo a change. Here, k e or K is the Coulomb constant (k e 8.988 10 9 Nm 2 C 2), q 1 and q 2 are the assigned magnitudes of the charges, and the scalar r is the distance between the charges. He was a contributing editor at PC Magazine and was on the faculty at both MIT and Cornell. Air exerts pressure, too, due to the weight of the air above you. Pressure is force divided by area. Power. How much horsepower is that?

\n

You know that

\n\n

so all you need to calculate is the average speed and the net applied force. What does force divided by distance equal? You know that F = ma, so you can plug in the values to get. Forces add up quickly when youre underwater because water is a heavy liquid. The applied force is the force exerted on the barrel by the person and it is responsible for the motion of the barrel. This is analogous to the way gravity behaves, with one important difference: the product of two masses is always positive, and gravity is always attractive. The force for a given charge will be constant anywhere in this field. You think its kind of small, but he claims it has over 100 horsepower. You whip out your underwater calculator to find thats about 230 pounds. Thats an interesting result power equals force times speed? In physics, you can calculate power based on force and speed. The distance formula in coordinate geometry is used to calculate the distance between two given points. The formula W = Fd shows the relationship between work, force, and distance. Now all you need is the average speed. Petra Wakefield is a writing professional whose work appears on various websites, focusing primarily on topics about science, fitness and outdoor activities. Then for the charge graph, I'm not sure what the units of charge even are. Yep, thats what it says. You can use the equation

\n\n

to find the average power. Braking Force Formula The following formula is used to calculate the braking force of a car given a speed, weight, and stopping distance.
