No. Force is required for accelerated motion, but not for uniform motion.
in the same direction as the object's motion.
Work is the product of force and displacement, where force is the effort applied to move an object and displacement is the distance the object moves in the direction of the force. The formula for work is: Work = Force x Displacement x cos(theta), where theta is the angle between the force and displacement vectors.
You need to know the component of displacement in the direction of the force. In the simplest model, Work = Force*Displacement (in the direction of the force). More complicated models will include friction, for which the mass of the object and the coefficient of resistance between the object and the surface are required. You could also include aerodynamic resistance at which stage the calculations get rather complex.
Work is the scalar product of the force acting on an object and the displacement caused by that force. In order for work to be done, the object must be moved in the direction of the force.
Work is defined as the product of force and displacement. If an object is not in motion, there is no displacement, thus no work is done by the force acting on the object. Work is only done when a force causes an object to move through a distance in the direction of the force.
Work done by a force when the force is in the direction of displacement is calculated as the product of the force and the displacement, multiplied by the cosine of the angle between them. Mathematically, work done (W) = force (F) × displacement (s) × cos(θ), where θ is the angle between the force vector and the displacement vector.
Work done by a force is zero when the force is applied perpendicular to the direction of motion of the object. Another scenario is when the force is applied but there is no displacement of the object.
buoyant force is the result of the displacement of the fluid an object is in. if a fluid is displaced by the volume of an object, the weight of the fluid being displaced is pushing up on that object
The component of the applied force that is parallel to the displacement of the object is the only part that performs work on the object. This is because work is defined as force multiplied by the displacement in the direction of the force.
Experiences a displacement in the direction of the force.
Displacement is the volume of fluid displaced by an object immersed in it, while buoyant force is the upward force exerted on an object immersed in fluid due to the displaced fluid. The magnitude of the buoyant force is equal to the weight of the displaced fluid, which is directly related to the volume of fluid displaced, or the object's displacement.
It is possible to do no work on an object if the force applied is perpendicular to the direction of motion of the object. In such a case, the force may cause the object to change direction but not cause any displacement in the direction of the force. Work is only done when there is displacement in the direction of the force applied.
