Work Equation:
From: | To: |
The work equation (W = F × d) calculates the amount of work done when a force moves an object over a distance. Work is measured in joules (J) in the International System of Units.
The calculator uses the work equation:
Where:
Explanation: Work is only done when the force causes displacement in the direction of the force. The equation assumes the force is constant and in the same direction as the displacement.
Details: Calculating work is fundamental in physics and engineering to determine energy transfer, mechanical advantage, and system efficiency.
Tips: Enter force in newtons (N) and distance in meters (m). Both values must be positive numbers.
Q1: What are the units of work?
A: The SI unit is joules (J), where 1 J = 1 N·m. Other units include foot-pounds (ft·lb) and ergs.
Q2: When is work considered zero?
A: Work is zero when there's no displacement or when the force is perpendicular to the displacement.
Q3: How does this relate to energy?
A: Work and energy have the same units because work represents energy transfer to or from a system.
Q4: What about angled forces?
A: For forces at an angle, use W = F × d × cos(θ), where θ is the angle between force and displacement.
Q5: Can this calculate negative work?
A: This calculator gives magnitude only. Negative work occurs when force opposes displacement.
