Net work is the total amount of work done on an object, taking into account all the different forces acting on the object.
Net work is calculated by multiplying the force acting on an object by the distance the object moves in the direction of the force. This can be represented by the equation W = Fd, where W is work, F is force, and d is distance.
In this context, weight refers to the gravitational force acting on an object. It is typically measured in units of Newtons (N).
To calculate the net work done on an object with a 394N force, you would need to know the distance the object moved in the direction of the force. Then, you can use the equation W = Fd to calculate the net work in units of joules (J).
Calculating the net work done on an object allows us to understand the overall effect of multiple forces acting on the object. It also allows us to determine the amount of energy transferred to or from the object, which can help us make predictions and analyze the motion of the object.
