Log in for more information. Say youre in your neighbors pool, waiting near the bottom until your neighbors give up trying to chase you off and go back into the house. 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. The impulse applied to an object is equal to the change in its kinetic energy, (b) acceleration, (c) momentum, (d) velocity. She holds a Master of Science in agricultural engineering from Texas A&M University. 3.

How much horsepower is that?

You know that

\n\n

so all you need to calculate is the average speed and the net applied force. Experimentally equivalent to gravitational mass.

in this case, "distance" means how far the spring has been moved The back of your hand has an area of about.

The law sometimes (if the mass of the body under consideration is constant etc) simplifies to (say in the x -direction) (2) F x = m a x. Enter the length or pattern for better results. A motorcycle traveled 250 kilometers in five hours. Now, if we consider the units of each of these three terms, work, force, and distance, then starting at the top, the unit of work is the joule, abbreviated capital . Dummies has always stood for taking on complex concepts and making them easy to understand. Okay, you say, getting out your clipboard.

The mass and velocity of an object impact how much kinetic energy it has. You know that F = ma, so you can plug in the values to get

Okay, so the force applied to accelerate the car steadily is 5,060 newtons. When you perform work, it generates kinetic energy. Forces add up quickly when youre underwater because water is a heavy liquid. One horsepower = 745.7 watts, so

\n\n

Therefore, the car developed an average of 78.0 horsepower, not 100 horsepower. He was a contributing editor at PC Magazine and was on the faculty at both MIT and Cornell.

That leaves only the final kinetic energy to calculate:

Plugging in the numbers gives you:

One horsepower = 745.7 watts, so

Therefore, the car developed an average of 78.0 horsepower, not 100 horsepower. Thus $1N = 1 kgm s^{-2}$ Force = mass times length divided by seconds squared. He has authored Dummies titles including Physics For Dummies and Physics Essentials For Dummies. Dr. Holzner received his PhD at Cornell.
