What else can I help you with?
Does the work you do on a book when you lift it onto a shelf depend on the path taken?
No. That's one of the properties of gravity ... the work required to go from one point to another depends only on the difference in height between the two points, and not on the path. A 'field' in which this is true is called a 'conservative' field. The electrostatic field is another one.
Is work done if you lift a brick?
Yes, work is done when you lift a brick against gravity because you are exerting a force over a distance in the direction of the force of gravity. Work is defined as force multiplied by distance in the direction of the force, so lifting the brick requires work to be done.
Is work being done when you lift a box?
Yes, work is being done when you lift a box against the force of gravity. Work is defined as the force applied over a distance, and in this case, the force you exert to lift the box is acting over a vertical distance, thus work is being done.
Which correctly describes why work is done when you lift a book?
-- If you're looking at a list of choices and not sharing it, then there's reallyno way for anyone here to help you pick the best choice.-- Work is (force) x (distance through which the force moves).In order to lift the book, you have to apply an upward force to it thatjust matches its weight, and you have to keep applying the force all theway to the table up to whatever height you want to lift it. So there's yourforce, there's your distance, and their product is the work that's done.
Explain why you are doing work on a book when you pick it up but not when you carry it across the room.?
The scientific definition of work is using force to move an object over a distance. When you use your hand to lift the book off the floor, you are going against the force of gravity that is attracting it to the floor in order to lift the book in the air, from one location to the next. However, when you carry a book across the room, you are not fighting a force. As a matter of fact, the book has not left your hand; therefore, you are not moving it anywhere. The tricky thing is to not think of of the book as moving across the room - YOU are moving across the room; the book is still sitting in your hand. Now, if you THROW the book across the room, that is different entirely.
What energy of a book on a shelf is equal to the work done to lift the book to the shelf?
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
Is t true the kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no
True or false the kinetic energy of a book shelf is equal to the work done to lift the book to the shelf?
false

What is the relationship between the work done to lift a book to place it on a bookshelf and the potential energy of the book on the shelf?
There is no direct relationship because the potential energy of the book on the shelf is defined relative to an arbitrary base line at which the potential energy would be zero. The work done in raising the book is the increase in the potential energy of book from however much PE it had in its previous location - for example, on a lower shelf.
What describes why work is done when you lift A book?
Work is being done when you lift an object because you are applying a force (lifting) parallel to and against another force (gravity). If you carry an object, you are still applying a force directed upwards, however your motion is perpendicular to gravity (as you walk to the east, for example). In this case, NO work is done, regardless of how far or how long you walk/carry. When you set the object down, again, your force is parallel to and with gravity. Therefore, work is done, however, in this case, it'll be negative.
How much work is done to lift 40kg of bricks to a height of 10m?
The work done to lift 40kg of bricks to a height of 10m can be calculated using the formula: Work = Force x Distance. The force required to lift the bricks is equal to the weight, which is mass x gravity (40kg x 9.8m/s^2). Plug these values into the formula to find the work done.
