1
Work done formula:
Answer & explanation
Correct: option B
W = Fs.
2
A 25 N force moves a box 8 m. Work done?
Answer & explanation
Correct: option A
W = 25 × 8 = 200 J.
3
Pushing a heavy box at constant speed across rough floor. The work done by the push goes to:
Answer & explanation
Correct: option B
Constant speed = no KE change. Friction transfers to thermal stores.
4
1 joule equals:
Answer & explanation
Correct: option C
J = N × m.
5
Force perpendicular to motion does:
Answer & explanation
Correct: option C
No distance in force direction → zero work.
6
Lifting 4 kg through 3 m (g = 9.8). Work done?
Answer & explanation
Correct: option C
F = mg = 39.2 N; W = 39.2 × 3 = 117.6 J ≈ 118 J.
