When a retarding force is applied opposite to the direction of motion, the angle between the force and displacement is 180 degrees, resulting in negative work done.

When the force and displacement are parallel, the work done is positive because the force contributes to the motion of the object in the direction of displacement.

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.

Defining work in this manner provides a clear and quantifiable measure of the energy transferred to an object by a force acting on it, facilitating precise analysis and calculation in various scientific contexts.

In cases where the force and displacement are not aligned, only the component of the force in the direction of displacement contributes to the work done.

No, work only has magnitude and no direction. It is a scalar quantity determined by the magnitude of the force and the distance moved.

The work done (W) is equal to the magnitude of the force (F) multiplied by the distance moved in the direction of the force (s), expressed as W = F * s.

In science, work is defined as the product of the force applied on an object and the distance moved by the object in the direction of the force.

Yes, if the bullock applies force to the cart and causes it to move, meeting both conditions, then work is done in this situation.

Displacement is crucial, as without it, even if force is exerted, work is not considered to be done according to the scientific definition.
