If a constant force of 2 Newton is applied on a body such that displacement of the body in the direction of the applied force is zero, then the work done by the force is _______.

The Correct answer is 0.

Key Points

• The work done by a force is defined as the product of the force and the displacement of the object in the direction of the force.
• The formula for work done is: Work = Force × Displacement × cos(θ), where θ is the angle between the force and the direction of displacement.
• If the displacement of the body is zero, then the work done by any force, regardless of its magnitude, will be zero.
• In this scenario, the force applied is 2 Newtons, but the displacement in the direction of the applied force is zero.
• Therefore, the work done by the force is 0 joules.
• This concept is important in understanding the relationship between force, displacement, and work in the context of physics.

 Additional Information

• Force
  • A force is a push or pull upon an object resulting from the object's interaction with another object.
  • Forces can cause an object to accelerate, slow down, remain in place, or change shape.
  • Forces are measured in Newtons (N) in the International System of Units (SI).
• Displacement
  • Displacement is a vector quantity that refers to an object's change in position.
  • It is the shortest distance from the initial to the final position of a point.
  • Displacement has both magnitude and direction.
• Work
  • Work is done when a force causes a displacement of an object.
  • Work is a scalar quantity and is measured in Joules (J).
  • Positive work is done when the force and displacement are in the same direction, while negative work is done when they are in opposite directions.
