Work Formula:
From: | To: |
Definition: Work is done when a force acts on an object and displaces it in the direction of the force.
Purpose: This calculator helps students and professionals calculate the work done when a force moves an object over a distance.
The calculator uses the formula:
Where:
Explanation: Work is calculated by multiplying the force applied by the distance the object moves in the direction of the force.
Details: Understanding work is fundamental in physics and engineering for analyzing energy transfer and mechanical systems.
Tips: Enter the force in Newtons and distance in meters. Both values must be positive numbers.
Q1: What's the difference between work and energy?
A: Work is the transfer of energy. Both are measured in Joules, but work specifically refers to energy transferred by force.
Q2: What if the force isn't in the direction of movement?
A: Then you need to use \( W = F \times d \times \cos(\theta) \), where θ is the angle between force and displacement.
Q3: How do I convert Newtons to other units?
A: 1 N = 1 kg·m/s². For imperial units, 1 N ≈ 0.2248 pounds-force (lbf).
Q4: What's a practical example of this calculation?
A: Lifting a 10 kg object vertically 2 meters requires about 196 J of work (10kg × 9.8m/s² × 2m).
Q5: Does this calculator account for friction?
A: No, this calculates ideal work. In real systems, additional work is needed to overcome friction.
