Now, if it was on an incline sliding down as you pushed it..
Work is the amount of energy transferred when a force is applied to an object and causes it to move in the direction of the force. It is calculated by multiplying the force applied by the distance the object moves in the direction of the force.
The unit of measurement for work is joules (J), which is equivalent to a kilogram-meter squared per second squared (kg⋅m²/s²).
When the force is not constant, work can be calculated by finding the area under the curve of a force-distance graph. This can be done by dividing the graph into smaller sections and finding the area of each section using basic geometry principles, then adding all the areas together.
Yes, work can be negative. This typically occurs when the force and the displacement are in opposite directions, meaning the force is acting against the motion of the object. For example, if you push a box up a hill and it rolls back down, the work you did would be negative.
Work is a form of energy and it can be converted into other forms of energy, such as kinetic energy or potential energy. The work-energy theorem states that the net work done on an object is equal to the change in its kinetic energy. Additionally, work done by a conservative force can be converted into potential energy.
