Work = (Force) x (Distance)
Since the calculation of work involves distance to the same extent as force, any force, no matter how small, can do any amount of work, no matter how large, by proper manipulation of the distance.
Work = F x D
or D = W / F
You want ---> 2W = (F/2) x Q
Q = (2W) / (F/2) = 4W / F = 4D
By pushing 4 times as far, half the force does twice the work.
vertical lift versus slope the work done is the same (force * distance), but with a say 30 degree slope you need only half the force but need to travel twice as far to raise the load the same height vertically
In order to reduce the magnitude of the electrostatic force between two charged particles by half, you canEITHER: reduce the magnitude of the charge on either one by 50% of its original value,OR: increase the distance between the particles to 141.42% of the original distance.
Pressure = (total force on an area) divided by (area of the area). Half the area and keep the force the same you get twice the pressure. half the force and over the same area pressure is halved. P = F/A
half its present value
No, half of twice is once.
Magnitude is brightness. As stars are further away they're dimmer. It may seem like a star that twice as far away would be half as bright but it doesn't work that way. Brightness falls off in proportion to the square of the distance away. A star that is twice as far away is one-fourth as bright.
work done is zero because force is toward the centre and distance is tangent to the circle so cos90 is equal to zero.[abbasia]
Semi annual payment means payment done every half year or twice a year.
weight It measures the magnitude of the gravitational force that attracts you toward the center of the Earth. It's not necessary to measure the magnitude of the force that attracts the Earth toward the center of you. Not only don't you care about that one, but we know that it's exactly the same as the first one.
Two and a half, surely.
Half of 50 is 25 and twice of that is 50. So 50.
If the doorknob were moved to the middle of the door, it would take twice as much force to open it than if it were at the edge of the door. With the mass of the door being equal. Moment = the force to open the door times the distance to the center of the hinges. If the distance were cut in half it would take twice the force to keep the equation true.
