Work Formula:
Power Formula (Force × Velocity):
From: | To: |
Definition: This calculator computes both work (force × distance) and power (force × velocity) based on input values.
Purpose: It helps physics students and engineers understand the relationship between force, distance, velocity, work, and power.
The calculator uses two fundamental formulas:
Where:
Explanation: Work is done when a force moves an object through a distance. Power is the rate at which work is done (work per unit time).
Details: These calculations are fundamental in mechanical engineering, physics, and many real-world applications from simple machines to complex mechanical systems.
Tips: Enter the force in Newtons, distance in meters (for work), and velocity in m/s (for power). All values must be positive numbers.
Q1: What's the difference between work and power?
A: Work is force × distance, while power is force × velocity (or work ÷ time). Power measures how quickly work is done.
Q2: Why is velocity used in power calculation?
A: Velocity represents distance over time, so force × velocity gives work per unit time, which is power.
Q3: What are typical units for these calculations?
A: Work in Joules (N·m), Power in Watts (J/s), Force in Newtons, Distance in meters, Velocity in m/s.
Q4: Can I calculate work without power or vice versa?
A: Yes, the calculations are independent. You can calculate work with just force and distance, or power with just force and velocity.
Q5: How does this relate to energy?
A: Work and energy are directly related - work done on an object changes its energy. Power is the rate of energy transfer.
