What is the equation to calculate the downward force of something?
Q. The tension force is 9800 Newtons. The object is 1000kg. The rate is 2m/s^2. I know this is cheating and all, but if you think it is cheating, then just give me the equation for downward force.

How can i make my hair smoothly grow downward?
Q. I was planning on growing my hair out a few centimeters above my eyes, but it wont grow strait. It tends to curl as it goes out. It's also a bit on the "puffish" side. My sideburns also tend to move forward. Is there a special way men with long hair make it grow smoothly downward?

What is the force exerted on the small piston during each downward stroke?
Q. An automobile having a mass of 1750 kg is placed on a hydraulic lift in a garage. The piston lifting the car is 0.239 m in diameter. A mechanic attaches a pumping mechanism to a much smaller piston, 1.50 cm in diameter, which is connected by hydraulic lines to the lift. She pumps the handle up and down, slowly lifting the car. What is the force exerted on the small piston during each downward stroke?

Q. You are travelling downward in an elevator and are slowing to a stop. How does the normal force on your feet compare to your weight at this time? How do you know?
Asked by mike - Fri Aug 17 12:35:39 2007 - - 2 Answers - 0 Comments

A. you weigh more right now than you normally would. when you slow to a stop, your body is moving, and the floor is slowing you down. it is slowing you down faster than you are falling, and your momentum creates more force. as you slow down, your body keep moving due to inertia, and thus you produce more force, thus weighing more. hope this made sense

Why do fluvial systems generally have a coarsening downward trend of grain size?
Q. This is a question for those adept to geology. In a grain size log versus depth, fluvial systems are usually distinguished by a coarsening downward or fining upward trend of grain size. Conversely, shallow marine systems have a coarsening upward or fining downward trend instead. I would like to know why this is the case. I believe it has something to do with prograding and retrograding systems, but would like a clear-cut explanation if possible. Thanks in advance.
Asked by Some Guy - Sat Nov 8 00:39:44 2008 - - 3 Answers - 0 Comments

A. The coarsness of the sediments is always a function of the energy of the transporting medium, Deltaic systems typically consist of several upward coarsening sequences because the delta progrades out into the ocean, over-riding the finer distal sediments. A river dumps the coarsest fractions of its load as soon as it enters a standing body of water as the flow rate of the stream decreases, then the finer fractions are carried further out and deposited at the toe of the delta lobe. As the delta lobe advances, coarser fore-set beds and later even coarser topset beds will be deposited over the finest sediments, giving rise to an upward coarsening sequence. If the delta lobe is abandoned due to river channel avulsion, the old lobe will… [cont.]

We just bought a house and our ceiling fan blades slant downward. Is this normal?
Q. The regulation height is seven feet for a ceiling fan, and the fan is at seven feet, but the blades are at six and a half tops. My fiance hits his hands if he raises them. It looks like the actual metal on the fan is slanted downward, not the blades themselves. The blades are sloping down farther than any other fan i have seen. When standing ten feet away, you can easily see the entire top of the blades.
Asked by unknown - Mon Feb 4 21:39:35 2008 - - 10 Answers - 0 Comments

A. Some ceiling fans of flimsy blade design do 'droop' down from turning in a perfectly level plane with the ceiling and floor as they should do. All ceiling fans have a 'pitch' to them--that is, they have a certain amount of twist in them with respect to the flat planes of the ceiling and floor. It is this twist that, when the fan is turning the blades in one direction, the air is caught by the upper edge of the blade and either pushed downward toward the floor or upward to the ceiling-- depending on the direction of rotation of the circle of blades. Ceiling fans that are designed to be able to be switched to change the rotation of the blades are called "switchables". Many older fans will operate in one direction of rotation only. On… [cont.]

What is the comparison of acceleration of a ball thrown upward to a ball thrown downward.?
Q. Physics. Is the acceleration of the upward ball the same or less than a downward thrown ball?
Asked by unknown - Sun Sep 6 11:45:45 2009 - - 4 Answers - 0 Comments

A. When the balls are in the air, whether it has been thrown upwards, or thrown downwards, the acceleration of both balls will be exactly the same, that is 9.81m/s downwards. The velocity of the two balls will always be different, but the acceleration will be identical.

Considering that both guys have the same build,strength,fist size and all other variables.
Asked by s s - Thu Jul 30 07:13:31 2009 - - 2 Answers - 0 Comments

A. Possibly, it depends, there is a limit to how fast your arm will be able to accelerate and at what velocity. You may be already able to reach the maximum speed and velocity punching upwards so the momentum would be the same. THe only way it would have a larger impact was if the final velocity is greater...which is to say it depends on whether human anatomy will allow for an additional acceleration of 9.8ms^-1

Q. A ball is thrown downward from a window in a tall building. The distance traveled by the ball in t seconds is s = 16t2 + 32t, where s is in feet. How long (to the nearest tenth) will it take the ball to fall 97 feet?
Asked by unknown - Sun Mar 14 17:31:56 2010 - - 1 Answers - 0 Comments

A. You need to use the quadratic equation to solve this equation. ax^2+bx+c=0 Just move the s to the other side: 16t^2 + 32t - s = 0 From that: a = 16 b = 32 and c=-97 Plugging into the quadratic equation: { -32 Sq Root ( 1.0240e+3 + 6.2080e+3 ) } / 32 = t x1 = 1.6575 x2 = -3.6575 You can't have negative time, so it has to be 1.6575 seconds.
