In this scenario, the work done is calculated as the product of the force exerted by the baby and the displacement of the toy car, with the work considered positive due to the alignment of force and displacement.
How is the work done when a baby pulls a toy car parallel to the ground, considering the force and displacement are in the same direction?

When a baby pulls a toy car parallel to the ground with a force, and the displacement is also in the same direction as the force, positive work is done. This is because the force applied by the baby contributes to the displacement of the toy car, transferring energy to it, which increases its kinetic energy, making it move.
