Net work is the total amount of energy transferred to or from a system. It is calculated by multiplying the force applied to an object by the distance the object moves in the direction of the force.
Net work is directly related to kinetic energy. The work done on an object is equal to the change in kinetic energy of that object. This means that when net work is done on an object, its kinetic energy will either increase or decrease.
Yes, net work can be negative. This occurs when the direction of the force applied is opposite to the direction of motion. In this case, the work done on the object will be negative, meaning that the object loses kinetic energy.
The angle between force and displacement affects the magnitude of net work. When the force and displacement are in the same direction, the net work will be at its maximum. As the angle between force and displacement increases, the net work will decrease, reaching zero when the force and displacement are perpendicular to each other.
The unit of measurement for net work is joules (J). This is the same unit used for energy and is equivalent to 1 Newton-meter. It can also be expressed in terms of other base units such as kilogram-meters squared per second squared (kg*m^2/s^2).
