* Work and Energy: Work is the transfer of energy. Positive work means energy is being added to the object.
* Kinetic Energy: The energy of motion is called kinetic energy. It's directly related to an object's mass and velocity: *KE = 1/2 * mv²*
* The Connection: When positive work is done, the object gains kinetic energy. This increase in kinetic energy means the object's velocity must increase to maintain the relationship between kinetic energy and velocity.
Example: Pushing a box across a floor does positive work on the box. The box gains speed (velocity) as you push it.
Important Note: The specific change in velocity depends on the amount of work done and the mass of the object. A larger amount of work will lead to a greater change in velocity. A heavier object will have a smaller change in velocity for the same amount of work done.
