So, all the nett work is done by gravity and friction does no nett work. Likes Soren4 FAQ: Rotational work done by static friction? 1. What is rotational work done by static friction? Rotational work done by static friction refers to the amount of energy required to rotate a stationary ...
Work Done against Gravity 4 - CPO Science 下载积分:3000 内容提示: Name: Date:4.1 Work Done against Gravity Any time you lift an object, you do work against gravity. We use the same formula for work that you already know (Work = force × distance), but it’s expressed in a slightly ...
The curl is typically used in describing work. If a rock is lifted 5 feet off the ground against gravity, work is being done. The curl can be thought of as a measure of how much work is done to move the rock along that line (whether it is curved or straight). The formula, althoug...
What is work and what is its formula? Learn the definition of work in physics and how to calculate the value of work done by a force using a...
When we lift a load through a height against the force of gravity by applying a force greater than the gravitational force, the work done on the body is eventually stored as the gravitational potential energy of the body. This brings us to the work-energy theorem. Work energy theorem states...
The rate of work done on the box by the person pushing is determined by the formula P=Fv, where F is the force and v is the velocity. The force of friction, gravity, and the net force are also taken into consideration in the calculations. The net force on the box is...

First we need to calculate the work done, which requires the force necessary to lift the truck against gravity: F = mg = 1000 x 9.81 = 9810 N. W = Fd = 9810N x 2m = 19620 Nm = 19620 J. The power is P = W/t = 19620J / 15s = 1308 J/s = 1308 W. Related Concept Elect...
Assuming each liter of water weighs about 1 kg and using (g = 9.8 m/s^2) for gravity, the work done (W = m x g x h = 200 x 9.8 x 5 = 9800 J). Time (T) is 10 seconds.Substituting the values into the power formula gives:...
