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 pulling a sled 100 m with 80 N at 30°
Answer: work done = 6,928.2 J.
What we know
- Force: 80 N
- Distance: 100 m
- Angle between force and motion: 30°
Step by step
- Given
- F = 80 N, d = 100 m, θ = 30°
- Formula
- W = F × d × cos(θ)
- Substitute
- W = 80 × 100 × cos(30)
- Result
- W = 6,928.2 J
