Force over distance
WebIn the more general case of a force which changes with distance, the work may still be calculated as the area under the curve. For example, for the work done to stretch a … WebThe numbers come from the fact that approximately, if you double the distance, you quarter the force. If you triple the distance, the force will be divided by 9. Generally, multiply the distance by n, the distance drops by a factor of n^2. In other words, you multiply the distance by 1/n^2. Now it should be clear why the law is called the ...

WebOct 19, 2024 · The position of the object, as a function of time is just. x ( t) = F 2 m t 2. and so the work done by the force, as a function of time, is just. W ( t) = F x ( t) = ( F t) 2 2 m. thus, the work done does depend on the time. Now, since the initial velocity is zero, the work done equals the kinetic energy of the object. WebSo, we only need to push the box through a distance of 585 m, which is still over five football fields long. Given the known speed of 0.25 m/s that will take us: 585 m 0.25 m / s = 2340 s \frac{585 \mathrm{m}}{0.25 …

I am looking for the distance x from the center of mass of a rod with I (cm) = 1/12 * m * l^2 were i can apply a Force F over a time delta t so that the rod does excactly one revolution before he is back at its original height. WebForces at a Distance. Gravity is a non-contact force. It acts on us 24/7, making sure we don’t float off into space. Magnetic forces are created by magnets and other magnetic materials. Even though the magnets don’t touch they exert a push or pull force over the other object. Electrostatic forces are seen when positive and negatively ...
WebThe mass has now increased in speed to twenty meters per second. It has fallen a total distance of twenty meters (average speed 10 meters per second x time elapsed of 2 seconds). So the work done by the force of gravity in accelerating the mass over the first two seconds is force x distance = 10 newtons x 20 meters = 200 joules.
