A body is moving in the direction opposite to the direction of force acting on it. The work done ___.
Work Done = Force × Displacement.
Here displacement is in the opposite direction of force applied.
Therefore, the work done will be negative.
A body is moved in a direction opposite to the direction of force acting on it. State whether the work is done by the force or work is done against the force.
(a) What happens to the work done when the displacement of a body is at right angles to the direction of force acting on it ? Explain your answer.
(b) A force of 50 N acts on a body and moves it a distance of 4 m on a horzontal surface. Calculate the work done if the direction of force is at an angle of 60∘ to the horizontal surface.
A force of 30 N acts on a body and moves it through a distance of 5m in the direction of force. Calculate the work done by the force.
A body is moving in the direction opposite to the force acting on it. The work done here is:
