For work to be done on an object, two conditions must be satisfied: 1. A force must be applied to the object. 2. The object must be displaced in the direction of the force.

Both conditions are met: a force is applied, and the book is displaced upwards.
When the displacement of the object is zero, the work done is also zero, regardless of the force applied. Mathematically, W = F . s, and if s = 0, then W = F . 0 = 0 joules.
When the force acting on an object is zero, the work done is also zero, regardless of the displacement. Mathematically, W = F . s, and if F = 0, then W = 0 . s = 0 joules.
Work is considered a scalar quantity because it has magnitude but no direction. While force and displacement are vector quantities, the product of the magnitude of the force and the displacement (in the direction of the force) results in a ...
When the force acts in the direction of the displacement, the work done is positive and is calculated as W = Fxs. If the force acts opposite to the direction of displacement, the work done is negative, and if the ...
The work done by a force is considered zero if either the displacement of the object is zero or the force acts perpendicular to the direction of displacement. In mathematical terms, W = F⋅ s ⋅ cos(θ), where θ is ...
Work is defined as the product of the force and the displacement of an object in the direction of the force. Mathematically, it is expressed as W = F ⋅s, where W is the work done, F is the magnitude ...
No, work is not done because the object must be displaced for work to be considered done in the scientific sense.
Yes, work is done because the bullock exerts a force on the cart, and the cart is displaced.
