The object has a velocity.
Explicación
## Step 1In physics, work is defined as the product of the force applied to an object and the distance the object moves in the direction of the force. This is represented by the formula:### \(W = F \cdot d \cdot \cos(\theta)\)where
is work,
is the force,
is the distance, and
is the angle between the force and the direction of motion.## Step 2For work to be done, the object must move in the direction of the force. This means that the object must have a velocity.## Step 3The weight of the object or whether the object is stationary or not does not affect the work done. The key factor is the movement of the object in the direction of the force.
