Understanding the Concepts
* Work: Work is done when a force causes an object to move a certain distance. It's calculated as: *Work (W) = Force (F) x Distance (d)*
* Force: A push or pull that can change an object's motion.
* Distance: The length over which the force acts.
Analyzing the Situation
1. The Force: A force of 12 N is applied to the screwdriver handle.
2. The Distance: The handle moves 0.3 m.
3. The Work Done: The work done is 3.2 J (Joules).
What is the screwdriver doing work on?
The screwdriver is doing work on the lid of the paint can. Here's why:
* The force from the screwdriver is applied to the lid. This force causes the lid to move upwards.
* The lid moves a distance as the screwdriver pries it open.
* Work is done: The work done by the screwdriver is the energy transferred to the lid to overcome its resistance and move it open.
Important Note: The work done by the screwdriver is not necessarily all transferred to the lid itself. Some energy may be lost due to friction between the screwdriver and the lid, or internal resistance within the lid.
