Simple Machines: Work

The video tutorial explains the concept of work in physics. It starts by illustrating that pulling a cow or pushing against a brick wall does not constitute work if there is no movement in the direction of the force applied. The tutorial then defines the conditions necessary for work to occur: the object must move, and the movement must be in the direction of the applied force. An example is provided using a lawn mower, which moves in the direction it is pushed, demonstrating the concept of work effectively.
