Observations:

• The work is the same even though the objects have different final speeds because Work is Force times the Distance, both of which are the same for each body.
• You can not tell from the speed of a body alone how much energy it possesses (its kinetic energy KE) or how much Work it took to get the body into motion. A small force over a long distance can do the same work as a big force over a short distance.
• Time is not a factor in determining the work, just the distance and the force along the direction of motion. The rate at which work is being done is the power output of the agent that created the constant force. The power output is largest for the lightest body since it takes the shorest amount of time to go the distance d.
• The work done by the force on an object increases the object kinetic energy (Work-Energy Theorem).
