What Is Work in Physics?
In everyday language, work is “something that needs to be done.” In physics, work has a more precise definition. Work is the amount of force required to move an object over a certain distance. Importantly, if there is no movement, no work is done.
The formula for work is:
Work (W) = Force (F) × Distance (d)
Where:
- W = work in joules (J)
- F = force in newtons (N)
- d = distance in meters (m)
This equation forms the work-energy principle, explaining how much energy is used to move an object.

Real-Time Examples Using the Work Calculator
1. Calculate Work
Suppose you lift a 6 kg backpack with a force of 60 N to a height of 1.2 m.
Given:
F = 60 N
Distance = 1.2 m
Calculation:
Work = 60 × 1.2 = 72 J
Result:
You did 72 joules of work.
2. Calculate Kinetic Energy
If the backpack moves at 2 m/s:
Given:
Mass = 6 kg
Velocity = 2 m/s
Formula: KE = ½mv²
Calculation: KE = ½ × 6 × (2)² = 12 J
Result: Kinetic energy = 12 J
3. Calculate Gravitational Potential Energy
Given:
Mass = 6 kg
Height = 1.2 m
Gravity = 9.81 m/s²
Formula: PE = mgh
Calculation: 6 × 9.81 × 1.2 = 70.632 J
Result: Gravitational potential energy = 70.632 J
4. Calculate Elastic Potential Energy
Given:
Spring constant k = 200 N/m
Stretch x = 0.15 m
Formula: PE = ½kx²
Calculation: ½ × 200 × (0.15)² = 2.25 J
Result: Elastic potential energy = 2.25 J
5. Work-Energy Theorem
Formula: Wnet = ΔKE + ΔPEgravity + ΔPEelastic
Calculation: 12 + 70.632 + 2.25 = 84.882 J
6. Calculate Power
If lifting takes 2 seconds:
Given:
Force = 60 N
Distance = 1.2 m
Time = 2 s
Formula: P = W/t
Calculation: 72 / 2 = 36 W
Result: Power = 36 W
