In physics, work is the energy transferred to or from an object via the application of force along a displacement.

This calculator computes work based on force, displacement, and the angle between them using the equation: W = F × d × cos(θ).

About Work in Physics

Work is a measure of energy transfer that occurs when a force moves an object. In physics, work has a specific definition: it is the product of the force applied to an object and the displacement of the object in the direction of the force.

Key Concepts:
  • Units of Work: The SI unit of work is the joule (J), which is equal to a newton-meter (N⋅m).
  • Direction Matters: Only the component of force in the direction of displacement contributes to work.
  • Positive & Negative Work: Work can be positive (force in the same direction as displacement) or negative (force opposing displacement).
  • Zero Work: No work is done when force is perpendicular to displacement (cos(90°) = 0) or when there is no displacement.
Work Formula:

The general formula for work is:

W = F × d × cos(θ)

Where:

  • W is the work done (in joules, J)
  • F is the magnitude of the force (in newtons, N)
  • d is the magnitude of the displacement (in meters, m)
  • θ is the angle between the force and displacement vectors
  • cos(θ) represents the portion of the force acting along the direction of displacement
Special Cases:
  • θ = 0° (Force parallel to displacement): Work = F × d (maximum work)
  • θ = 90° (Force perpendicular to displacement): Work = 0 (no work done)
  • θ = 180° (Force opposite to displacement): Work = -F × d (negative work)
Work in Different Contexts:
  • Constant Force: W = F × d × cos(θ)
  • Variable Force: W = ∫F·dr (the integral of force with respect to displacement)
  • Work-Energy Theorem: The work done on an object equals the change in its kinetic energy

What is the Work Calculator?

The Work Calculator is a handy tool designed to help you calculate the work done on an object. In Physics, work is defined as the energy transferred when a force moves an object. This calculator simplifies the process by using the formula: W = F × d × cos(θ). With just a few inputs, you can find the work, force, or displacement you need.

Understanding Work in Physics

Work is a key concept in physics. It measures how energy moves from one place to another. Here are a few important points about work:

  • It involves force applied in the direction of movement.
  • The unit of work is the joule (J), which equals a newton-meter (N·m).
  • Negative work occurs when the force opposes the movement.
