Work done can be defined as ______.

The correct answer is force × displacement.

Key Points

• Work done is defined as the product of the force applied to an object and the displacement of the object in the direction of the force.
• The formula for work done (W) is: W = F × d, where F is the force applied and d is the displacement.
• Work is a scalar quantity and has units of Joules (J) in the International System of Units (SI).
• Work done is positive when the force and displacement are in the same direction, and negative when they are in opposite directions.

Additional Information

• Force:
  • A push or pull upon an object resulting from the object's interaction with another object.
  • Measured in Newtons (N) in the SI system.
• Displacement:
  • The change in position of an object.
  • It is a vector quantity, having both magnitude and direction.
• Energy:
  • The capacity to do work.
  • Measured in Joules (J) in the SI system.
• Power:
  • The rate at which work is done or energy is transferred.
  • Measured in Watts (W) in the SI system.
