direction of motion, it does positive work on the object, increasing its kinetic energy.
If the force moving an object points partially in the opposite direction of the object's motion, work is considered to be negative. This is because the force is acting against the direction of motion, reducing the overall work done on the object.

When the force acting on an object points at least partially in the direction of motion, the work done is considered to be positive. This is because the force is helping to move the object in the same direction as its motion, resulting in a positive work output.
At least two objects are needed for a force to come into play. A force is a push or pull exerted on one object by another object, so there must be at least two objects interacting for a force to be present.

Nothing will happen. Nothing will happen. I think.
The buoyant force is zero when the object is just touching the liquid. As the object displaces more volume, the buoyant force increases until the object is completely submerged. Once the object is submerged, it doesn't matter how deep it is, the buoyant force remains constant.
the least force
When the force acting on an object points at least partially in the direction of motion, the work done is considered to be positive. This is because the force is helping to move the object in the same direction as its motion, resulting in a positive work output.
Work = Force * displacement * Cosine of the angle between Force and displacement.. Here, that angle would be 180 degrees Cos 180 degree = -1 Hence work will be negative Work (W).

At least two objects are needed for a force to come into play. A force is a push or pull exerted on one object by another object, so there must be at least two objects interacting for a force to be present.
A fixed pulley allows you to lift an object with the least force because it changes the direction of the force without providing any mechanical advantage. When using a fixed pulley, you only need to exert the same amount of force as the weight of the object being lifted.
There is only one kind of line, but there are a few other line-like figures in the same family. Line: An object defined by at least two points and extends infinitely in both directions Ray: An object defined by at least two points, has a definite endpoint, and extends infinitely in one direction Line segment: An object defined by at least two points and has definite endpoints
