The physics
In physics, work has a precise meaning: force applied along a distance. Push a box 5 m with 200 N and you've done 1,000 J of work — energy transferred from you into motion and friction heat.
Work pushing a trolley 50 m with 30 N
Answer: work done = 1,500 J.
What we know
- Force: 30 N
- Distance: 50 m
- Angle between force and motion: 0°
Step by step
- Given
- F = 30 N, d = 50 m, θ = 0°
- Formula
- W = F × d × cos(θ)
- Substitute
- W = 30 × 50 × cos(0)
- Result
- W = 1,500 J
All results
