because when walking on the road with the bucket, the hand has an upward force on the bucket, which can keep the bucket from falling, but the bucket does not move a certain distance in the direction of the force (that is, upward), Therefore, work is not included
If an object is moving vertically upward at a constant speed, the work done on it is related to its weight. The specific relationship is: w = GH, W is work, G is the weight of the object, and H is the distance of the object moving in the direction of force
2. It can be calculated according to the conservation of energy, and work can be converted into energy.
just like in the real world. Now you have a house and a car, what do you need money for? You're very satisfied. Hehe
The formula of work: w = fscos α Where f is the pull, s is the distance, cos α It's the angle between the force and the distance
work is also called mechanical work. If an object is affected by a force and has a displacement in the direction of the force, we say that the force has done work on the object. Work is a physical quantity that represents the accumulation of force to displacement in physics. Like mechanical energy, work is also a scalar, in joules
(1) if the object moves at a constant speed, the total work of the object is zero(2) if the resultant force on the object is f, and the displacement direction of the initial motion and the final motion is the same as F, then the total work of the object is greater than zero
(3) if the resultant force on the object is f, and the displacement direction of the initial motion and the final motion is opposite to F, then the total work of the object is less than zero
Note: there is a difference between the total work and the work of a certain forceYou're talking about wealth value.
wealth value is a virtual currency known by the Internet.
it can be used to ask questions, or to exchange phone bills and physical gifts in the mall.
